puritan psm156

@xcr33pshowx - I believe Jaguar Audio out of Seattle might provide trials on the Puritan units. BTW, I highly recommend the Puritan product. Without question it improved the quality of two different systems in my home. 

+2 Puritan

My experience was different. I noticed reduced dynamics, pinched highs. Soundstage was not great. I ran it with Classic and Ultimate cords and even had AQ Hurricane on it for few months. 
Plugging amplifier into it reduces the sound quality even further. It may be ok for source components especially ones with switch mode power supplies or ones with inadequately designed linear power supplies. 
I would recommend a passive Shunyata power conditioner over the active puritan. 
Best to try before buying or buy used.
