V-Cap ODAM: What the Future Sounds Like


The evolution of the capacitor has led manufactures to utilize copper foil in the finest of capacitors. There’s a new kid on the block that might turn the capacitor world on it’s head but it’s too small and too affordable to be a copper foil cap. At first sight, one can brush off this new cap as just another insignificant option to the plethora of capacitors that are already on the market. The ODAM is much more than just another capacitor, it’s revolutionary.

The VCap ODAM capacitor is quite possibly the most transparent capacitor on the market. It will allow your system to perform in a way that you’d never expect from a capacitor upgrade because we’ve become accustomed to the limitations of conventional capacitors. It unlocks the potential of your system and you can experience your music collection in a new way. The ODAM will show you that there’s so much more information in your music. You have no idea what you’ve been missing.

My first experience with the ODAM was when I tested it in my backup DAC, the MHDT Pagoda. This DAC is known for having a wide soundstage but I had no idea how much wider it can get when the restraints were removed by the ODAM. It was quite a revelation. There are so many adjectives to describe what improved and how much they improved. I’m going to fast forward that part to tell you that the key takeaway here is that I’m able to hear and experience the recording more than ever before.

The second revelation that the ODAM provided came from a power conditioner tweak. Use your favorite search engine and search for "Audience conditioner". You can find several images of the internal circuitry of these power conditioners and notice that there are capacitors installed in parallel to the receptacles. You may also notice that each capacitor is slightly larger than the next within the same series of receptacles. This is a simple trick to filter noise at different frequencies. I’ve used this technique in my conditioner for several years now and I’ve concluded that Teflon caps were the best cap type in this position but then the ODAM came along. I installed a 0.47uf and a 0.1uf ODAM @ 600V (one cap on two of the three receptacles of my conditioner) then I had a listen. This was an "OH SH*T" moment. I did not expect this much of a leap in sound quality. The noise floor vanished. My system was already very dimensional but now it’s like wearing 3D goggles for my ears. It was shocking to learn how awful my system’s A/C was all these years.

I was a teenager the first time that I experienced a soundstage through a stereo system although I must admit that I was under the influence of cannabis. I really enjoyed how the high accentuated my hearing ability but I quickly grew out of this smoking phase in my life. I eventually got a job, I bought a car, and had a sound system installed in it.

I followed what members of an online mobile audio forum were doing by installing SEAS or Scanspeak/Vifa drivers into the vehicle. That’s how I was introduced to high end audio and that’s when I realized that this hobby is the gateway into experiencing an audio high without being high. I chased that high ever since.

Most of us in this hobby can relate to the chase for better sound but the chase recently came to a conclusion for me. I’ve finally reached that sonic high that I’ve been chasing and the ODAM helped get me there.

The ODAM couldn’t achieve so much alone. It allows my Pass XA25 and the JCAT FEMTO USB card to shine. The ODAM is the closest thing to no capacitor. It imparts no tonal coloration whatsoever. There is no limitation to sound stage width and depth other than what your system is capable of.

So much has already been said about the ODAM and it’s posted on the VCap website. I encourage you to have a look. Those comments are spot-on.

Hi Alex,

Let us know what you think of the sound. Are the caps still in your amp? How do the caps measure in terms of tolerance?
@alexberger Please keep us updated regarding the replacement cap. 

There's a possibility that I may upgrade my DAC in the near future. If I decide to keep my current DAC, I will upgrade the 20uF cap in the PS to two 10uF ODAM caps in parallel. Let's see what happens. 
@qauntumpot Thanks for posting such a detailed review with follow-ups. I have not applied CuTF decoupling caps to the ODAM in my system, but I plan to sooner or later.

@gunhold and I spoke on the phone earlier in the year to discuss how I approached the conditioner mod. A couple of weeks later, he called me back and said that he upgraded the receptacles and caps at the same time. The mods made a vast improvement to his system, and I knew they would. He sent me a photo of the project and a short clip of the completed conditioner. His DIY skills are fantastic and looked as though Audience themselves performed the work.

I experimented with the orientation of the capacitors in the conditioner. Caps perform their best when AC enters the capacitor from the inner foil and exits the outer foil. The opposite is true when used as coupling caps in the signal path. The soundstage shrinks and everything condenses to the center when the caps are incorrectly installed in the conditioner, so mind the outer foil.

I’m going to digress a bit here: if you think that the ODAM and receptacle upgrades are terrific, wait until you install an Akiko Audio Harmonizer Unit into the conditioner. It’s a grounding component that you connect directly to the IEC ground. It’s that simple to take your system to the next level and beyond.
@jmolsberg Clarity is an adjective that I would use to describe the ODAM but never grainy. These caps might be revealing other weaknesses in your system. You might get better synergy if you switch to warmer tubes that don't reveal as much detail. 

Also, point the speakers straight forward and then slowly begin adjusting the speakers inward as you listen to correct the soundstage problem. Your speakers maybe pointing inward too much. 

I'll message you to inquire further. 
I’ll have to take pictures of the ODAM in my conditioner the next time that I open it which may happen soon if I purchase a syringe of PPT Total Contact.

The leads for the ODAM were not trimmed. I folded the leads back onto itself and lightly twisted them to create a larger gauge that helped the receptacles clamp onto them.

Make sure that the receptacles can be removed from your conditioner. You may need a torx screwdriver to remove the center screws from the rear of the unit.  

I can help you perform this upgrade if you live in Southern California. You should consider upgrading the 3 receptacles also. My conditioner has a Furutech GTX-D NCF, a Cardas, and a SR Blue receptacle. All 3 of these receptacles are much, much better than the stock receptacles. The Furutech NCF IEC inlet was another big upgrade as well.
Perfect! I'm in Los Angeles and I don't  mind a short weekend drive to help you out. 

Open the unit to make note of the capacitor values and take pictures. Try loosening the outermost receptacle to make sure that it's not permanently fixed in place. 

I recommend that you upgrade the receptacles as well. If you are interested, send an email to your retailer of choice and ask if you're able to return the receptacles in the event that we're not able to perform the modification. We can also install them into your walls if you haven't already upgraded any receptacles.
