Heard the Computer Audio Design GC1

 Ground control unit.  It's a holy cow are you kidding me moment.  I was told bout the unit by a bunch of my computer audio friends.  One of my favorite audio stores, Audio Connection in NJ is one of the few dealers in the US.  Johnny Rutan was telling me about the ground control units when he auditioned them and said they make a big difference in sound and not just a small one.  

All I'm going to say is that it's a must listen to product. I think it comes with a money back guarantee, but I'm not sure if that holds true in the US.  For those who follow the CAD company in the UK, knows how good their products are.  Grounding is so important and I'm going to be getting one of these CG1 units as it's better than what I've heard from Nordost and a couple of other companies.  Yes it's that good in all areas. 

when you lower the noise floor you just get much better sound in any system.  This is one of the best usages of money into most any priced system.  JMHO, but worth checking out.

After I had reviewed the SONORE Signature Rendu SE for Dagogo.com they came out with the systemOptique upgrade; it's an Ethernet to optical converter leading to the Sig. Rendu. That was a shocking moment as well for the same reason, as the noise carried on the Ethernet connection was banished. Elimination of noise is a legit way to boost a system's performance. 

Audiophiles seem zany to talk about how "black" backgrounds are, and how much noise there is during quiet passages, etc. But, when you have a good enough system all these things are revealed quite clearly, and they make a big difference to the perceived quality of the recording and sound of the system. It's very much like the new lenses for the Hubble Space Telescope, in that when you can refine and refocus the system so many details that were previously obscured now are resolved and the image created is all the more stunning.  :)

Yes, I use a special deal for that also.

Looking forward to your discussion of it when used in your system. :)

I was with Peter (CTsooner) at Audioconnection when we had an audition of the GC1.
I can attest to a deeper, more nuanced reproduction. Very subtle information became more apparent. 
I found it hard to believe that such a non-active component could affect sound reproduction- but, Hey, this is high end audio, and there is a lot that seemingly defies reason, but provides better listening.

That really was an eye opener wasn't it?  I'm about to pull the trigger on getting one.  It's been the best under 2k tweak I've ever heard.  You can use one on each server, DAC and preamp.

The recommend using one on the earth to the system/power conditioner if you can afford it.  For me, I'm going with the CG1 on the server/integrated DAC as that most probably will be the biggest sound difference in my system.  I already run fairly clean power from dedicated lines to the system.
