My experience as well with both the 136 and 156.
@vinylvalet - In the future, I'm planning on purchasing an additional Puritan for my second unit. I'd welcome your thoughts on how the 156 improves overall performance. Did you start with the 136 and then upgrade?
Thank you for relaying your experience. I have heard very good reports about these products. I have also read reports from people saying they didn't hear much of a difference.
Power conditions vary very widely -- in different regions, towns, homes -- and most people don't have the equipment or knowledge to know how noisy their power situation is. In other words, without that variable, the efficacy of the product remains a case-by-case guess.
I went from a PSM 136 to PSM 156 and the difference with definitely obvious with a lower floor noise which allows more low-level detail to immerge...😁
Good to be reading the feedback on here as I too have been researching around for a solid power conditioner... so looking forward to testing and using a PSM 156 with a bunch Puritan Ultimate cables for my system. Having guys like Steve Huffington, OCD Mike and the host of "HiFi Cave" on YouTube endorsing it doesn't hurt either. 👍
