Recommendations for Power Conditioner Upgrade From Old Shunyata Hydra 8

waltersalsa, What kind of power cord did you get to connect to your Shunyata Everest 8000?  Were you replacing a conditioner?
Before I posted, I researched Audiogon to see what I could find in peoples' recommendations.  I did find that some of the AQ 5000 & 7000s have a hum sound.  I saw one Audiogon post where someone also has a Hydra 8 and compared it to an AQ Niagra 5000 and could hear no difference.
I am pleased with my system's sound.  In this hobby, always wondering what can make it sound even better that I can afford.  In order not to overspend, I have to condition myself to the point where "I am satisfied--this is good enound."
For those interested, in a recent email, Shunyata's customer rep was kind enough to layout the upgrades in their equipment since my Hydra 8 was made.  This is what he said.

Many differences.  Here is a list of the main ones.  Improved conductors that are of larger gauge and newer type, specifically VTX conductors.  Pure copper buss system over the older wired buss (less junctions).  Enhanced and more effective surge modules. Greatly improved filter networks (between yours and now we've had over a dozen improvements in design and the current models use a spin off of the medical filter used in our medical devices).  In Denali and above, we have outlet to outlet noise reduction and all outlets are high current using the new technology chambers we call QRBB modules. All units now have the CGS (chassis grounding system). Most all units also have improved outlets, either the SRZ1 outlets or the custom built pure copper CopperCONN outlets.
The whole spectrum will be improved. Dynamics, soundstage, detail, blacker background, lowered noise floor, improved bass/body. I'm confident that any aspect of listening that you notice and listen for in your system will be improved upon noticeably.

Thanks everyone for your responses.  It's hard to find someone who has a 30-day trial period for a power conditioner.  Music Direct maybe.

I think The Cable Company does PCs now. They built their business on lending.

I am using a Shunyata Sigma v2 XC power cord on the Everest. Again, not cheap, but it's one of those things that once you hear it what it does, you know you don't want to take it out. The Everest is absolutely dead quiet, with an inky black noise floor. I am generally skeptical of dealer/customer rep hyperbole, but in this case, it is justified, at least in my experience. That description from the Shunyata rep is pretty much on the money. The improvements are comprehensive and readily apparent.

I replaced an Inakustik 3500P, which is also excellent but just not on the same level as the Everest, nor should it be expected to be given the differences in price. I have nothing but the highest praise for each of these products.

dweller,
Actually with my Niagara 7000 I found the Hurricane HC power cable sort of tame. My DIY power cable is much better.
