Best line conditioner???

Jayctoy, I have not heard that particular PS Audio unit and do not doubt that you heard an improvement. I would like to hear that unit some day.

I have to agree with you Clueless and Subaruguru, if your amplifier(s) has a good enough power supply and you have good dedicated lines with good connections and outlets, you will likley hear less improvement with a line conditioner. I do not use any conditioning on my amps, just a dedicated 20 amp line with a good outlet and power cord. I only use the conditioner on my digital now (and if I ever get my phono stage back, I may try it on that as well).

I have had a bunch - Tice, Chang, PS Audio PP300, Audioprism, ESP, Sound Application XE-12 and the Audio Magic Stealth. Some were better than others, some not worth the money. But, in MY SYSTEM, the new Audio Magic Matrix (with it's new power cord which is an integral part of the system AND included in the price) beat them all and by a fairly decent margin. I didn't want to believe this flimsy, lighweight, cheap-looking box could possibly be anything but snake oil, but I'll be darned, it was the FIRST PC in my system that didn't do some bad with the good. It simply improved the noise floor, it smoothed the digititis and it DIDN'T negatively impact the transparency or dynamics like the others did in one way or the other. But, as always, YMMV.
