Pass Labs INT-150 with Power Plant Premier

The PS Audio re-generators seem to be fine, especially with the multi-wave setting options. Cannot say for a fact that the multi-wave is better, but it is different in a pleasant way. Long story short the PS Audio products do not seem to bring anything ill to the table.

Some back ground: The power amps have for many years been built with tuned noise rejection circuits ahead of the transformers in anticipation of legislation that deals with noise on power lines.

These tuned circuits frequently do not benefit from added reactance that many passive aftermarket noise canceling products provide. The do no physical harm, but in general do not serve the music.

It has proved most prudent to answer these questions on a one on one basis.

Interesting! I had a PPP and found it doesn't work with my tube monos rated @650Va per mono. Theortically it should work ... The PPP would heat up and fan screaming loud. Out of couriousity, I borrowed a 2nd PPP and plug each mono to a PPP and the same heating up / fan result.

I've had many PS Audio products and found PPP their best effort but there are superior alternatives in the market. In general, I found active PC alters the sound and the sound sounds processed. Finally settled on a passive unit with 2 dedicated 20 amp lines that restores the natural tone without any current limiting problems.

I bet your new Pass Labs amp sounds better plugged directly into the wall.

I'll leave it plugged in the wall about a couple weeks to acclimate to the sound before trying and comparing the sound plugged into the PS Audio.

The two reasons that Pass Labs recommends plugging directly into the wall are that (1) many power conditioners contain chokes that impede instantaneous current draw, thus hurting the resulting dynamics, and (2) many (all?) Pass amps have their own built in RF noise filtration.

I have had the X600.5 amps for several years and found that the Synergistic Research PowerCell 10SE to improve the sound greatly without hurting dynamics, while the Shunyata V-Ray did dull the sound somewhat. So it is case by case.

Dedicated lines did very little to the sound of my sound. Certainly far less than the Synergistic.
