Pwr. conditioner necessary w/dedicated AC lines?

OK guys, now I'm REALLY confused. I have been using a PS Audio P300 (all of the latest revisions) as a mainstay in my system for about four years now. It seemed to always work wonders in a previous set-up, in a different house/room, which DID NOT have dedicated AC lines.

Fast forward to the present were I now have the good fortune of having a dedicated room with independent AC runs throughout. I have been using the P300 for the last 3 yrs. or so in this room. Well, on a lark, I thought I would try to run my tube CD player (Droplet) direct to the AC instead of through my power plant (which was set BTW on "tube") and WHA-LA! It sounds a LOT better! ?? What's up with this???
The dynamics spang to life and there is better extension in the top end. Again..what gives here???

The possibly scary part of this whole scenario is - what if I have been "chasing my goofy audiophile tail", all this time, swapping, changing, selling and buying gear based on an erroneous negative sound effect that was possibly brought on by my Pwr. Plant on my front-end gear?!? Arrgh!

Just to be sure that this was not a fluke isolated to my Droplet, I also tried a different CD player that I have on loan and the same effects applied (sounded better "straight" into the wall AC).

Can anyone else relate a similar effect? Advice?? Comments??? Thanks.

I would like to reactivate this thread now that a little time has passed to perhaps get some new feedback. I am still using my P300, but ONLY for my BAT VK3i preamp (I am still running my CD player "direct" to the wall, which again is a isolated dedicated line).

My question still remains - those of you with dedicated AC lines - what is your experience with using power conditioners? Which application seems to bring the most improvement? Amps, preamps, CDP, etc? Also --- what are some of the "hot" brands of conditioners, that don't cost over $2k retail?

Thanks!

i was most surprised when a silver circle PP1 v 3.0 made an audible / drastic improvement in line noise on source gear, esp given that i have dedicated lines w/ twisted romex, and its only 8ft of romex b/w breaker and AC outlet.

point being: you cannot know in advance.

the more resolving your system, the bigger the improvement. but dedicated lines are the best bang for the $.

I installed a dedicated line for my system, then added the Jon Rische AC line filters to clean/quiet the power. http://www.geocities.com/jonrisch/surge.htm One for the front-end and one at the power amps.

The owner of a very high-end audio manufacturer (which shall remain nameless) recently asked me to evaluate their new single component power conditioning devise. My audio system is plugged into 4 dedicated 20 AMP lines, so power issues never crop up. When I placed this new product in front of the CD player, the result was awful! It literally sucked the life out of the music. As suggested in earlier posts, power conditioners are useful ONLY when needed.

This has been answered on my behalf by Kgproperties when he said:

I've been posting similar responses to this question since I joined Audiogon in 1999. Only passive devices such as Quiet Lines do any good without harming the sound. Quiet lines are just caps that scrape off a tiny amount of noise. Not a big improvement but also not big cost :^).

Quiet lines represent the limit of what I'm willing to introduce into my electrical system. If you have a big problem, they are not going to "fix" it.
