Brett I am using Chang Lightspeeds with good results. Aside from their conditioning properties, they have large internal MOV's (metal oxide varistor) as well as input & output fusing for transient protection. I don't know about getting that level of high current protection for $300, though, unless you buy used. Their model 3200 ($250) is a 20 amp rated unit with 2 digital filtered & 4 analog filtered outlets which I use for source components. The 30 amp rated model 9900 Amp ($750 w/ floor spikes included) I use mainly for amps of course. Among several others, Chang also offers a nice model 6400 Iso combination unit, which is a Stereophile recommended component & will handle more components (at I believe higher current rating?) so that might be just what you're looking for. They definitely improved my sound even considering that I already have upgrade AC cords & decicated AC line. One thing to note though, is that any of my heavily filtered upgrade AC cords seem to work better straight into the line vs. through the additional Chang filtering, while unfiltered cords do better plugged into the Chang's. Stereophile also recommends the A.P. Power Wedge although I've no experience to share in that regard.
Best power conditioner for 300.00
I have a dedicated 20 amp circuit run to a hospital grade outlet for my system. ( Electronics are Krell and Speakers are Dynaudio ) I love the sound but I like to leave the system on and I am a little worried about spikes or surges. So I would like to put something between the outlet and my electronis. I don't feel the need to go crazy because the power is very clean as is. As long as I am going to get surge protection I might as well get a little conditioning. I have looked at Chang Lightspeed , Audio Power, and Tice. I would appreciate any feedback. Thanks in advance- Brett
