Puritan PSM156

After reading so many positive reviews and experiences, I finally bought a PSM156 myself (with upgrade to Classic plus power cord) to replace an Audio Quest Niagara 1200. My set already sounded quite nice, but probably caused by mains fluctuations and external influences from power supplies and electronic devices in the area, it was a lot less pleasant at certain times. It just wasn't consistent in sound quality. The Puritan almost completely solved that problem right out of the box. But moreover, even if it wasn't properly burned in, it improved the SQ in several aspects already. 

I experience a (slightly?) deeper sound stage, it is less cluttered, less chaotic, especially with orchestral music. In addition, I hear a deeper and more tightly defined bass and there is more spaciousness: the acoustics of the space around the instruments are displayed better and more beautifully. Any sharp edges in the high tones of some instruments have also virtually disappeared. All in all, it has undeniably brought more calm and tranquility to the music.
As you can imagine, I am already very happy with it!

By the way, my set consists of a Cambridge Audio CXN V2 streamer, a Matrix Audio X-Sabre Pro dac, a (vintage) Marantz CD 17 KI Signature SACD player, a Cayin A88T MK2 tube amplifier and finally a set of Martin Logan's Ethos hybrid electrostatic speakers (with active subs).

Loving what my Puritan PSM156 and Ultimate power cable have done to my system.

questforhifi: "Not really my goal to sell you on another more expensive conditioner, but rather just point out the puritan restricts dynamics."

I've found the exact opposite, especially since I bought one, and it has over 1000 hours of use.

I also recently purchased the PSM156. I also have my high current power amp plugged into it and don't notice it restricting dynamics at all. Very happy with this purchase. The only negatives I have found was the 20 Amp power socket (Can't use my other 15-amp power cords) and I wish it had 8 power sockets in the back instead of 6. 

I have the same experience, the PSM156 simply offers much more dynamics than I have ever experienced before. Sometimes I am suddenly startled by an unexpectedly loud passage in music I know very well 😁

I now have Puritan filters on both of my systems. Without question, both units improved the clarity of each system. I am plugging my amps directly into the Puritan, along with all upstream components. 

When funds allow, I’ll purchase the ultimate power cord and see how that impacts my primary system as a test. 
 

I guess it is system dependent, but do want to report I am a happy customer. My enjoyment of music has gone up since adding the 136 (first) and now 156 device.
