Best AC line conditioning devices?


Name your fave and any comparisons done. I'm particularly keen on this as I've experienced some great results (and some flubs) but I can't audition all. I admit to being extreme for isolation/conditioning for digital.

Thanks Prcinka. I just looked up the "review" by MARSHALL NACK in Positive Feedback issue 71. He claimed 'magic' and stated "Bottom line: If I had an unlimited budget, I'd sooner purchase the HB Acrylic than any power distributor or conditioner on the market." Wow! It would be nice to know the distributors and conditioners he has investigated?
Ptss,

I have only heard a Sound Application at a show. It was a $20,000 item that impressed no one in the room.
Interesting Sabai. Did you have the chance to listen to the system with and without the SOUND APPLICATION unit? $20,000 is a lot of money so I'd have high expectations. Do you remember who it was displayed with? Appreciate your input.
I used to own an Acoustic Revive RTP-6 Ultimate which is more of a high end distributor, but claims to offer some conditioning. The RTP uses top flight cryo'd Oyaide R1 wpo's and sounds fast, detailed and neutral/natural. I recently upgraded to a Gigawatt PC-3 SE Evo conditioner which was a significant upgrade. This condition has excellent engineering and build quality. In terms of sound, straight out of the box I noted the following improvements in random order; - smoother sound (more liquid), blacker background, more body, inner details, more detail in general & slightly improved dynamics. I'm told this conditioner needs around 200hrs to open up and settle down, so the best is yet to come!
Ptss,

Yes, we listened with and without the unit. It was in a Raidho room at the A/V show in Singapore.
