Shunyata or Synergistic for power conditioning?

Hamburger, I have the feeling that you are going to have to find a dealer that carries both brands and listen for yourself and/or have them describe what they hear, and the differences.

@hamburger;
I recently purchased the Shunyata Denali D2000T.
The HD3 power cord (I use to own a D3 and D4) will work on the Denali but you will need a 20 amp IEC feeding the Denali. If you don't own a 20 amp IEC power cord you could buy an adapter 15 to 20 amp IEC from VooDoo Cable for example: https://www.audiogon.com/listings/ac-cables-voodoo-cable-iec-adapters-15-amp-or-20-amp-cryo-treated-...
They do work very well and I have never experienced any loss of sound quality.
I found a gem in the rough that I'm currently using to power my Denali, it's the Silver Ghost power cord: https://www.audiogon.com/listings/ac-cables-6-silver-ghost-custom-made-silver-rhodium-woven-power-co...
I had a custom Silver Ghost made with 20 amp Wattgate IEC's. It's a very good power cord that is relatively inexpensive, but competes with power cords easily costing thousands of dollars in my opinion, and I have owned those power cords. BTW the Ghost power cords are built with impeccable craftsmanship, I'm very impressed and just ordered a second one last night. Being cryogenlitcy treated, they do take some break in hours.
I'm in no way connected to or benifit from any of the manufactures mentioned above, I'm just trying to pass on my thoughts to anyone that reads this.
Happy New Years to all!

Dave, I think on the power conditioner and my Integrated amp I prefer the Silver Ghost over the Blue and/or Yellow CT power cords. I will say that I need more listening time to be more spacific. And of course I still believe the CT cords are very good and I still use my Blue and Yellow since I'm working with two systems.

Dlcockrun, thanks for your kind words...

Seems to me that jmcgrogan2 (another very credible source as there are many on Audiogon) has actually owned a couple of the power conditioners being discussed here and I’m sure he would have some good information to share.

Hamburger, you can’t go wrong with the HD P3. At this point in time I believe the Silver Ghost (high current) produces a wider, deeper sound stage and more micro detail presented in a very musical fasion.

Thanks for the update! :-)

Where did you pick up your Sigma NR from?

20 amp cord I assume?

Sounds interesting fsonicsmith. I look forward to hearing your thoughts on your new set up when the time comes :-)

Thanks for the update!
