Power filtering – Furutech or Puritan Audio?

Thx - the PSM 156 gets a lot of love!

I'm looking for a modest but effective power filter in a second system, more modest than the Accuphase PS-530 in my main system that replaced a PS Audio PP12 power regenerator. 

I think the REF I5i is made by Furman, not Furutech...

Sounds like you are enjoying the PSM 156 (not PMS!).

Thx - I will look into Shunyata Research - I was unfamiliar with them until recently.

Thx - I took the plunge and ordered a Puritan Audio PSM 156.

Sound intriguing!

Though the ASR review includes a myriad of measurements, it fails to mention how the PSM 156 impacted the sound of music in an audio system.

Surely any assessment of audio equipment should include listening to complex musical passages - actually auditioning the equipment, not just measuring it.

To conclude that "there is no indication or logic that would tell us that it can make an audible improvement" is baffling without actually listening to music on an audio system with and without the unit in the chain.

Being seemingly objective without any subjective assessment is missing the point:  how does it affect the sound of music in an audio system?.

What a hilariously brilliant analogy - thank you!

I finally had a chance to test out my new Puritan Audio PSM 156 in two of my systems.  

The effect of the PSM 156 was very apparent - a silent black background with clearer ambient sounds from the room acoustics in the recording, improved clarity, detail and soundstaging. It felt like a veil had been lifted between me and the musicians. I heard new subtleties in very familiar recordings and greater detail with less smearing of the edges of the high notes of the piano and soprano sax. Certainly a big improvement over no power conditioning or filtration.

I then compared it the PSM 156 to my PS Audio PP3 and PP12.  The PSM 156 clearly bested the PP3, but the PP12 was much closer.  The PSM 156 was a little smoother sounding than the PP12 with slightly cleaner articulation of the high notes of the piano.  I would give the PSM 156 the edge over the PP12.  They both sound good, but the PSM 156 sounds a little better.  It is not really a fair comparison because my PSM 156 is not broken in, and the PP12 is.  The PSM 156 is bound to improve.

Sounds like a wonderful solution for a homeowner, but alas, I live in a condo townhouse...
