Puritan PSM156

"Rotel RSX-1067 receiver"  *facepalm*

I’ve had the PSM156 for a few days. I had a 20 amp dedicated circuit installed. Between the two…I think I prefer going directly into the wall with the dedicated circuit. The sound without the PSM156 is un-tweaked. I think the performance of the PSM156 may likely be system dependent. I can say the build and design is nice…the socket clamping force is marginally lean (could be tighter for my liking). I experienced some elevated noise with my Sony TV plugged into it. So…it may be that it’s designed for audio only not necessary AV set ups. I have 30 days to return it….albeit I just placed it into my rack I don’t know that I’m compelled to keep it. I may just get a power distribution box by Voodoo Audio…& call it a day. It may be mind over matter…but I think it’s doing something ever so slightly to the overall sound of the system and I prefer my system as is…just seeking a blacker background and the dedicated line’s come notably closer to achieving it. I barely hear any audible noise with my ear placed right against the speaker. Lumin U2 mini>Line Magnetic 32 DAC>Sugden A21SE.

@twinski66 if this unit is new —and if the power cord being used (Puritan Ultimate?) is also new— PLEASE give the unit or the pairing at least 10 days of on time before deciding… But I do agree with you, that this device may be system dependent, as it seems to show some tonal weakness in some, to one extent or another ‘lesser’ gear, that people then end up not preferring. Some noise and/or distortions we can be so used to (and perceived as warmth, musicality, etc.) that when they are gone the system is not preferred. I’ve seen the 156, in general, being favored in systems costing more than the ones where the unit is not favored.   

I’m going to finally get the Puritan 156 for my reference system. I’ll then move my current Puritan 136 into my office system.

@jriggy - Thanks for the recommendation on Ultimate cable. Eventually I’ll also pick up one for my reference system to go along with the 156. 

which would be the better upgrade, ultimate cable or groundmaster city?
