Mrtennis, I've tried all the previous line of PS Audio products, Chang Lightspeed, BPT, all Shunyatas with exception of V Ray, Audience Adept, various Bybee, caps on AC outlets, may have forgotten a few.
I would say the Shunyata Hydra 4 impacted the dynamics the least. And yes, I found some conditioners colored in the way you described. The Hydra 8 was just the opposite, warm and somewhat soft focused, I suspect the FeSi.
The BPT is least colored PC I've heard in my system.
Barbapapa, I've heard good things about the Equi-tech, transformer based, same as BPT. I like the BPT products because of build quality and Plitron transformers, quite unique design in the 3.5 line. Still, in your price range the Son should be a good choice.
Mapman, yes, the better filtering power supply should benefit less from PC.
