Here is the complete review I did on another forum in case anyone is interested.
About three weeks ago I received the Shunyata PS8, their entry level power strip which becomes a line conditioner on par with a Hydra when you plug in the Defender, a circuit with 30 filters embedded. In addition to the Defender, I received a Venom HC which is the 20 amp 10 gauge version of the Venom cord and one that had been specifically designed to connect the power strip to the wall. The outlet is an Oyaide GX+ I received from Tonepub connected to a 10 gauge Romex dedicated line to the switch box. This device replaced a Monster Cable HTS-5000 I had used before and had been out of the system for about a month. I also ordered the Stainless Steel Feet option (SSF) which look gorgeous although I do not have the desire to remove them to hear any sonic effect.
Shunyata recommends putting in around 5 full days of burn-in (running a fan) which I did but really only got to serious listening after two weeks of use. I did notice big changes immediately and then a nice increase after the first week. Once I had a handle on that, I plugged in the Defender at the outlet (per Shunyata recommendation) and so we have two weeks of use on the Defender. The Defender was a little grainy sounding at first then smoothed out, just as Shunyata said would be the case.
Fit and Finish: As one might expect from a $700 power strip

this is exceptionally well made. Fine parts from Hubbell cryo'ed outlets to better IEC connector. You have to see the stainless/brushed aluminum look in person. It's very beautiful for a power conditioner. The Venom HC is beefy and well made with beautiful semi-clear connectors on the end. The build quality is simply A+, particularly at this price point.
Bottom Line on Sound Quality: This is an amazing device which dramatically lowered the noise floor of my system. As a result I can hear more of everything. It also cleaned up some hashy sounding noise in the high frequency area which I would hear on certain digital tracks. Some detailed observations, most of which stem from the lower noise floor:
**Very clear, open sound all around. Convinced the noise floor has dropped significantly.
**Much more bass out of the 1.7s now. Really fantastic. Although my speakers don't go below 42hz, this is more than I have been hearing.
**Imaging seems to have improved. On some tracks where there is distant percussion, it now seem more solid.
**Pacing seems better. Things feel a little more "lively" but not in a hifi way, more natural.
**Lots of detail on guitar recordings. I was listening to Paul Simon's first solo effort and the guitars were so natural.
**My classical recordings (mostly cello/violin/piano) sound closer to the live performance.
I hope those of you considering this device will find this review helpful. Note that sometimes MusicDirect will offer up package deals with a little bit of a discount.
Overall, this product has exceeded my fairly high expectations. Seems every time a plug in a Shunyata cable or device the sound gets better. Not a bad record of performance.
P.S. Today I am listening to the Dialoghi CD from Yarlung Records. There is definitely more weight to Elinor Frey's cello on the Bach Suite No. 1. The lower noise floor is a real asset.
