Power Plant Premier vs. Hydra V-Ray Comparison

You should test each component individually with both units. I have found the Premier generally improves things but specific components could prove to be an exception.

For you PS Audio Premier users, any issue with the fan turning on? My friend has one and the fan is pretty loud.

I don't think my fan has ever gone on but my total load is problem < 400 watts. Never noticed any heat to speak of unlike the P300 which could probably cook bacon.

No fan noise at all on my PPP. Mine is silent all the time. And I have my entire system connected! I heard PS Audio has a replacement for the noisy fan and fixes the problem for free. Contact PS Audio directly.

I need to make a correction for my previous comment regarding PPP vs Vray. I dont how it changed its performance whether it is the power cord connection to the main a/c plug or the unit itself, but the character changed drastically after 20 hours of playing and Vray has got all the synergy and musical aspects much more efficient than PS PPP. PPP when compared to Vray, seems to overkill some frequencies so it is more aggressive and forward and creates some listening fatigue. Both units are having a black and silent background, however vray's soundstage realization is one step ahead of PPP. Vray is having a more effortless way of playing the music without sacrifising the dynamics. The tonal palette is acoustically more consistent and neutral. Of course these are my and some of my friends -who listened the both of them- observations and related to my setup. It might be different for another audio setup. In my setup, vray replaced PPP, and PPP is for on its way to a different setup of one my friends.
