Best line conditioner???

Well, I would recommend Tice for build quality + sonics (both fantastic), but seeing as they just went out of business... I wouldn't recommend them so eagerly anymore : ( They made some of the best.

ps - they can make a huge difference... as for Monster, check out this closeout on www.hcmaudio.com:

Monster HTS-2500 Power Filter $154.95

If any of your equipment is in the least bit current hungry then stay away from the Monster stuff. It made my VAC preamp muddy in the bass and actually increased the noise floor.

Audio Magic mini stealth is $500. Used for $375.
Also Exact-power used to be sold be www.av123.com.

I keep saying it, and so does T.A.S.! David Blair's Custom Power Cord Line (line conditioners and power cords) is full of some amazing AND AFFORDABLE gear! His products have won more T.A.S. Golden Ear awards than any other single manufacturer, as well as the ONLY two-time Golden Ear award for a single product! 'Nuff said.

Hi Mr. Parrot, TAS likes it so that is the final word? Nuff said? Come on. It may be a good place to start, but unless you assemble the reviewer's exact system including his room, you are unlikely to get the same results.
