These are something special out of the box.
Congratulations....you have a great product here.
It transformed my ARC 17se into a reference product...
Very musical with substantially better timbre, natural, richer textures, greater focus with more air.
Smooth and detailed.... with better bass.
Stage has greater focus with images more life like with greater air and separation.
Musical and free from grain and glare.
Greater decay and natural timbre of the piano keys...just delicious.
I listen to pure music now ... ODAMs are simply "SUPERB"
Congratulations, Chris.

Initial impression is a bit more texture in the treble, ambient air, space, great attack.  Overall, smoother without any compromises.

I notice I can turn up the Plasma significantly AND "NOT hear" THE Plasma tweeter.  The notes seem to sustain better, hearing the instruments resonate (acoustic guitar).  Listening before was the plasma at 9:00.  Now at 1200 with no overload in the treble.  Significant....

First the "beta" capacitor <ODAM Prototype>, then the OIMP as we have those at baseline perceptions.  I was able to turn up the Plasma to "full smoke"  with (beta) cap and no harshness.  With the OIMP, 12:00/halfway, and then it overloads. My speakers are 89dB, Plasma tweeter is 95dB. 

I am in "audio shock"... sound could not be more different.   Classical guitar is exquisite.  Body, attack, wood resonance.  Going to listen more....

Very transparent and musical overall. Seamless transition tonally.  Female vocals were just magical...

A league of its own.  More.....no, a lot "more" resolution than any other cap used. Once heard, if a system is resolving enough, a breakthough product. 

Just so fast, with great clarity that is just startling.  One piece, a dvd concert, the drummer just lightly brushes a triangle.... Very clear with the Beta cap, but so delicate, no exaggeration. With the <well-known brand> film/foil, the Triangle is virtually absent...the drummer brushes it....nothing is heard......no contest....

It is just so coherent and the top end is just so complete with musical nuance and focus.  Cymbals are pinpoint with great ringing overtones.  Sheer magic.  Visualizing the contact is easy.  Very believable.  So much better than <well-known brands X & Y) they barely get a glimpse of <beta cap’s>  taillights..... a knockout....

My friends who visited are fresh back from the Newport Show and remarked the top end I am getting exceeded everything at the show with the exception of the MBL, and it was close, but mine did focus and image better overall.  One is a drummer, the other a long time audiophile who has a grand piano in his house, and surrounded with musical talent. They were amazed at the resolution and information with no hint of being aggressive.  They loved the sound....

The beta cap just continues to sound more smooth, textured, and detailed and refinement still intact.  The <well-known brand> was "splashy" and Beta is so focused, and real sounding.  Cymbals sound like a small stick striking an object.... <well-known brand> more like several sticks...just not believable. 

They seem to be evolving to more textural purity, and less grain, in spite of the low level to start with.  <comment pertains to additional burn-in>

Haze / grain is gone, quieter background, focused / solid images, all elements of the music are better separated, bass has a solid image in the sound stage, a veil was lifted which makes the music seem louder, a lot of detail is revealed similar to CuTF; very enchanting, sound stage is 3 dimensional. 

Every improvement that has been noted is similar to having added a pair of CuTF <V-Caps> into my system.
For their size, they will be a dream for speaker manufacturers.

First impression from Jim.....
Fwd:......Wow!!!!!!!!! Freaking amazing...
I spoke with Jim, and he is in a bit of shock.  He has tried so many different caps, he is familiar with their character in a direct coupled configuration. He said "this has the highest resolution of any cap, ever, he has heard, and the most believable texture...just amazing".  He is smitten, seduced, and downright in love with these caps.....

He used it for his plasma tweeter.  He had the new <other well-known brand>, and really liked it.... until he tried the new cap...no contest

<OEM speaker manufacturer’s comments>: Just have to say these new caps are mind blowing. They are so much better on the plasma tweeters than anything I have tried, and I have tried a lot. You have a real winner here.

....so pristine clean, uncolored....stunning...
The caps still amaze me with the focused clarity without an edge to the music.....Very real and brilliantly organic.  I just heard the Pete Escovedo band at Yoshis....stunning dynamics of live horns, but I thought of the caps on how they get out of the way of "live, real" sound reproduction, while there.  Just getting a few steps closer to the main event....

I just had a friend over last night who is 1st trumpeter in a jazz band.  He brought over 5 albums, we played all of them....A/B sides. After we finished, he said "it was the first time he heard what he hears playing live.  The trumpet extension on top was very lifelike, all the energy, space, but no edge"....he was bowled over.....

There is magic in those caps.  I believe that until now, due to size/space limitations, cost, etc., the tweeter cap has not been given the priority it should have.  The entire note is shaped by that leading edge.  Speaker manufacturers are going to line up to hear these, and put them in all speakers worthy......

The component tested/Beta evaluated was to be a capacitor, 2.0uf in my tweeter.  My situation is unique in that I use Dukane Plasma Tweeters, which require only a 2.0uf cap in line on the (+) speaker lead, effectively rolling things off at approximately 3.5khz, and open on top.  I use it as a Super tweeter, even though it is starting in the upper midrange area  and going up.  I use an L Pad to match with the rest of the speaker.  I have used them to great effect with Aerial 10T, Magnepan 1.7, Legacy Whisper, Nestorovic 5AS MK IV, and my JBL 1400 Synthesis Array. 
I set up a system of quick disconnects so I could mute the preamp, change the cap, and be listening again in 1 minute as the cap is in the power supply, not in a cabinet. 

I have tried many capacitors in this position, and am still amazed by how uncolored the "Beta" tweeters are...they just "tell it like it is" and are honest, and so musical.  I had my tweeters mic tested, and they tracked the microphone curve from 5k up to 28k, the mic limit, to within 1/10 of a dB......Very accurate.  They likely go up to 50k, but hard finding mics that go up that far.

I have used European Silver caps, German caps, caps known for clarity, Oil caps, even in metallized propylene, copper with wax, Oil caps, and on. Where am I leading, you ask....

Well, those Beta caps I reviewed came in "A" form, which were very good, forgiving, grainless, and easy to live with.  They removed any glare and were highly musical.  The equal of the best qualities of all the caps I listened to.....until....I got version "B"......and something happened....something unusual.....the capacitor disappeared, got out of the way, leaving me speechless, this after a mere 20 hours listening, (they did get 300 hrs. machine break in first I should note).  The detail was smooth, full, informative, lifelike, and mesmerizing with an abundance of information.  I cannot impress on you enough, the amount of information, micro-detail, space,  these caps release.  Song after song, the newly discovered sense of space, attack, focus, bass articulation... yes, bass was captivating, taking me down the "I cannot go back" path.  Comparing with other caps on video concerts allowed me to see and hear what was happening.  Some details were completely omitted by some caps.

The leading edge of the note, if slow, dull, or lifeless, will pollute the entire sonic picture, if not by sins of commission, then by omission.  If the leading edge  is intact, the whole note frame remains intact, the emotion, transient attack, jump factor is present,  and what a joy it is to listen to.  If by now, you want some,  well, good and bad news...

I do not know how the rest of these caps were used in the beta testing, as we are all blind to application, and results, but I can say that if they are the same with other tweeters, midranges, and circuits,  as they were with my tweeters. Audio just took one giant step forward.  I feel they are revolutionary.  They are the size of a small cap, but sound like a great film cap.  They are 25% -50% of the size the other 2.0 caps are I used.  I typically like copper or Silver caps but a 2.0 is the size of a beer can, and cost a small fortune.  New choices are coming, fellow audiophiles.  Above all, trust your ears.

The resolution and "completeness" to the music at low volume levels was the big surprise.  A lot of dynamics, and nuance were present at very low levels.  Just a plethora of information.   AJA is so full and textured now, it is like tubes in texture, but speed and control of good SS.  Not sounding like SS or tubes.  I anticipate this can be listened to at much lower listening levels and not feel the need for louder music in search of dynamics.  The stage depth is crazy deep and instruments laid out very precise with air and space.   Very positive initial impressions. .. fun......

Musical textures and colors are abundant. A beautiful way of getting out of the music's path. 

Magical, forgiving, like the OIMP, but more texture and bloom.  Bloom, without the loss of detail.  Seductive in many ways.

These will make a very big splash. They can make a modest piece of equipment sound like something 4-5 times the price with a simple part change, providing no major flaws elsewhere.  These reveal a real bottleneck in sound reproduction.  A breakthrough product in every way.  

Companies like <several well known, ultra high-end speaker manufacturers> will just freak out when they hear how much better their speaker can sound.  This should justify a Mk II version, and a 25k upgrade price....and for once, worth it.  The improvement is profound......

Now that the "Beta" caps are in, they clearly are special.  They took a while to get settled in, but are very complete.  The biggest difference is the focus of instruments is so good.  Small cymbal strikes sound focused, delicate, have an authentic ring, that, on lesser reproductions sound like a diffuse splash, with little delicacy.  The stage is grand, wide, deep, and spacious.  Will listen further....

Actually hard to hear the cap sound.  Each recording is so different now.  The "Beta" caps just leave so few clues to a sonic print..
I am now listening to more non-evaluation music,.... music,  which I do not want to ruin with repeated plays.  Up is the old war horse, MOFI Jackson Brown,  "The Pretender".  This is a very unusual sounding recording with a thin vocal EQ, and sibilance, almost over the edge, but great instruments.  Any drift/lean to the thin side there, and it is unlistenable.  A very tough test to be sure.  

Sibilance is not gone, but the rough edges are gone on the vocals, and there is some body now, very tight focus, and quite believable, and quite extraordinary.  The harp in the background "Linda paloma",  is pristine clean, every pluck clear, dynamic, and sounding like a real harp, with great space.  The instruments sound world class, the vocals could have used a better mic, or different EQ, but in spite of this, still stunning.  Strings are silky, sweet, very real sounding.  Superb in so many ways.  Like going from a 1k phono to a 10k phono preamp.  Really, that big of a jump.

The EAR 834P truly deserves a great place in phono preamp standing for MM/47k loading.  Only after hearing the V-Capped CJ can one appreciate the improvement.   The CJ was 50-60% of the EAR pre "Beta" caps.  Post "Beta" caps, the roles are nearly reversed...the 834 is only 50-60% of the CJ.  With the "A" caps the EAR IS 80% of the CJ, with "A" caps.

The "Beta" capped CJ is just stellar in every regard...space, speed, detail, nuance,  and just so very close to the "real thing" ...it is just spooky.....

Not just a big leap forward are these caps,  but also amazing is what lesser caps can do to a signal....and it's not pretty....a bigger bottleneck than one would imagine.  Lesser caps can be very much the bottleneck philes fear.

The ability of these caps to disappear, and leave very little trace of their sonic print is a very big deal....for all of audio.....hopefully they have the level of resolution to appreciate these.  These will clean the window...hopefully the view is a pretty one.  Modest quality of components may not fare well....

About  the preamps and caps, the difference was so obvious, an untrained ear would have no difficulty hearing the difference.  It was that profound.

Cap update, there is subtle refinement and improved delicacy, just adding more instrumental 3D presence.  Very wonderful at this point.....a league of their own.......

There has never been a high-quality cap this compact.  Very cool....

Also comparing my CJ SS oil - capped VCAPS (B) and the..... SS just beats my superb tube phono.  I thought the warmth and texture of tubes would nose ahead, but they were texturally very close, with the bottom end and top end extension going the VCAP Beta way.  Just more "alive" jump factor, delicious texture, superb low end control and body.  Note separation is magical.  No smearing at all.  The tubes leave less space between instruments.  Magical phono......

After installing the Beta caps, I noticed that the sound became more dynamic and 3 dimensional. I get a sense of a 3D image even though my chair sits in front of the left speaker about 3 meters away.

Manufacturers and the DIY scene will no longer have to sacrifice internal cabinet volume or use outboard crossovers to achieve high quality sound.

Haze / grain is gone, quieter background, focused / solid images, all elements of the music are better separated, bass has a solid image in the sound stage, a veil was lifted which makes the music seem louder, a lot of detail is revealed similar to the CuTF V-Cap; very enchanting, sound stage is 3 dimensional. 

These caps are going to shock a lot of people.  So much texture and body, with the detail and resolution...everyone's dream combo
The caps keep getting better.  Very liquid now, but no sacrifice in resolution.  Very detailed, micro-detailed, spacious, just hard to give a sound to them.  They are, what the recording is...

The mid-range is now, very textured, more space around performers, deeper stage, more articulation, and upper extension on up spot on.   Overall, a very live performance feel with vocals just glorious.  This 1600.00 preamp just hosed my 3500.00 preamp from top to bottom, and reminds me of the 24k CJ GAT that was just in my system.

V-Cap ODAM capacitors

An upgrade of very significant proportions.  This little preamp equals or exceeds everything I have heard below 10k....and more above that.  
I have to admit that I am still impressed by them.

Curiosity got the best of me and I installed the 1uF pair in my A/C conditioner. The first thing that I noticed was the noise floor...what noise floor? Where did it go? It seemed as if my listening chair was floating in outer space exposing the black background of the cosmos. The stage became well layered. Imaging gained focus and was slightly enlarged. This is only the beginning because the caps should still require more burn-in time which will bring improvements or changes to the sound.

We tested many different “hi-end” capacitors on the rebuilt Dukane plasma tweeters, and the ODAM were not only the best for the money but the best period. The level of resolution was simply not matched by any other cap. There was no loss of musicality- just a clearer window into the amazing capabilities of the plasma tweeters. The results were the same with ribbon tweeters, just more natural resolution than any other capacitors. There also seems to be a sonic signature with most every cap but the ODAM series seems to transparently pass the music through adding very little of its own sound.

Compared to lesser capacitors they simply sounded more present and real.

The ODAM series has been a revelation and they are physically small and priced well below their performance level which is just icing on the cake! Thank you for all your efforts the ODAM capacitors have made all of my speakers better.

These ODAM caps seem to take the individual qualities of the <several well-known capacitor manufacturers'’ best series> styrene, and a few others, gelling them into one musical presentation.  They are certain to challenge any cap at any price for musical authenticity.  Hearing is believing.  My advice ...buyer beware...once heard, there is no going back.  We have been doing it all wrong for many years...parts matter...not only equipment swapping.  I just capped a modest QS preamp, taking it way above its price point.  In fact, my 5k plus Class "A" preamp sounded mechanical in comparison.  They are that good.....

A compelling combination of palpable performers, incredible resolution, and space galore.  A big slice of the real thing....

I want to give you a follow up of thoughts and comments regarding the ODAM series. The 2.2uf ODAM caps were installed as bypass caps to a 100uF cap in a crossover network of my Ellam Flex 3-Way speakers. In fact, the Beta <original prototype> were previously installed in the same location. There was a night that my son was watching an episode of Stranger Things listening through the Ellam Flex 3W.  There's a scene where someone knocks on a door. My girlfriend gasps and said, "Oh my god! It sounded like someone knocked on the actual TV." I responded, "Those are great speakers," and she just stared at them in amazement. The dynamics and dimensional imaging made that knock sound so real. I was so happy to learn that my girlfriend is not completely oblivious to this hobby.

In direct comparison to the Beta, the ODAM is even more dimensional and more transparent in the sense that sounds are more impactful when the recording calls for it. Just like the Beta, the ODAM doesn't impart a particular flavor in the way copper foil caps, for example, can be slightly warm or slightly "rich" .

My new speakers are finally complete as you can see in the pictures. These monitors use the new Scanspeak Ellipticor tweeters and they are incredibly revealing. Having 3.3uF ODAMs in the tweeter circuit is a dream come true. The sound stage is immersive and dynamic. I find it difficult to turn off my system and get errands done even though my system has a lot of burning in to do. My system has a new High Fidelity CT2 SPDIF cable, a new DAC, and new speakers so I'm not yet hearing what the system is really capable of. I will have to update these comments when the new components settle. 

The more I listen to my system, the more glued I am to the chair. There is no "lack of emotion". I feel more connected to the music than I've ever been. The ODAM capacitors are simply the most audibly transparent capacitors that I have ever experienced. People who expect a certain sound from oil filled capacitors will not expect this much transparency. 

I can't wait to hear the reactions from the audiophile world when you release these products.

One feature of the ODAM (initially experienced in the Betas) that I don't think I have mentioned to you is the ODAM's ability to place images to the far edges of the sound stage. I first witnessed this in a song where the female voice appears off center to the left and her echo appears off center to the right. The ODAM presents her initial voice in the same location but her echo is placed way far right. I thought that the Beta 50s might have malfunctioned because the imaging to this song was always similar no matter what component was upgraded or modified. I quickly realized that the Beta 50s broke the chains restraining the sound stage and a revelation to stereophonic sound was achieved. That day I experienced a true sound stage and it really is an experience. The panoramic imaging allows the stage to appear vast and unlimited. Details are true to life. The ODAM have brought this hobby into the 21st century. I would like to purchase a pair of 4.7uf if you have any available. 

The ODAM will indeed be seismic, and have many manufacturers playing catchup, others not even trying.  They are so much better, the gap is not narrow.  Could have been called the Seismic cap as well.......but ODAM is perfect. When OEM's like <well-known ultra-high end speaker manufacturers> try the cap, they will be just blown away....

Preamp update.  The differences are a top to bottom improvement in texture, transparency, and image dimensions and spatially placed instruments.  Very life like.  More information without any peaks.  Metallic rings ring with a realistic decay, not the common abrupt end to ringing.  And still smooth.  Very vividly beautiful. 

The only thing I would add is that until now, we have just accepted what we could get in a high value capacitor, in that great film caps in a 3.3, 2.0, that could handle 600v were beer can size....until now.......and the redefining  what detail is available now with the ODAM has to be experienced.  Detail now, is a very different definition as this version of detail is .....ironically....smoother, no edges to the notes, silky frames to the notes, yet exceptionally informative.  More transient attack, but longer rings on cymbal strikes, and texture to the whole frequency.  A more complete musical envelope.  The ambient sound of a recording Hall is very easily heard, providing more relevant musical information.  After using the ODAM, I realized how much of an imprint my old caps were making on the music.  These caps must be heard by those seeking all they can get from their music....a new Reference.

The ODAM that are used as output coupling caps for the DAC are approximately 70% of the capacitance of the DAC’s original caps. The change from 6.8uF <well known capacitor manufacturer> to 4.7uF ODAM gained so much in soundstaging and imaging, with no loss in bass response. My system now utilizes 3 pairs of ODAM. With each ODAM installation that I've performed, the soundstage increases in width and depth, the imaging becomes more dense and 3 dimensional, and the most stunning feature on the ODAM capacitors is it's instrument separation. It feels as if I can swim in the soundstage because it sounds so real and layered with the soundstage wrapped around me. My system is so exciting to listen to now. 

It is imperative that every new ODAM user must re-evaluate their speakers toe-in angle to truly experience their system's newfound level of transparency. Face the speakers forward to experience a vast soundstage as if a panoramic photograph came to life. Angle the speakers inward and you'll experience 3-dimensional imaging and density that will leave you glued to your chair. Nevertheless, the detail unleashed by the ODAM is startling. 

We've been using the new ODAM's for some time now in our preamp buffer and after a few days of break-in these caps open up and reveal a level of detail, bloom, dynamics and musicality that is a pure joy to listen to. Wonderful caps. Highly recommended.

ODAMs are simply glorious. I played Norah Jones, "Nightingale" 10 times repeatedly I never got sick of it, yet I hadn't played her for over 5 years...

If the ODAM caps were able to speak words, they would utter "We will rock you"....and mean every word.  They have rocked my musical world and have me listening to components with new awareness of just how important every single link is.  Just 1 weak link is all it takes to bring everything down.  I am afraid now, this will be the strongest link and I have to bring every thing else up to this standard.  Not easy.....Realizing the full potential of the ODAM are ......well in the future.  They have just started sending a shock wave through the audio world.  A legend is being born.....  Be ready....
