Pass Labs INT-150 with Power Plant Premier

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.

Petrushka, thanks for that helpful info. I am very much enjoying the int-150 in the wall. At some point I may try it in the PPP. I'm in no hurry or even feeling any urge to do so.

I'm really enjoying the music as is...

I exchanged emails with Pass Labs about their preamps, and while on that subject they mentioned the one power conditioner which they have found to make the biggest impact is the PS Audio power plant.

Positive or negative impact?

Given the context, I think they meant positive impact
