Power filtering – Furutech or Puritan Audio?

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?.

I’ve purchased and kept the Puritan 136 and 156. Both were significant system upgrades. I wonder if some folks who denigrate the use of power filters actually have any first hand experience with these sorts of products. 

"I once went to an apple pie contest. Judging was performed by a panel of experts, some with 30 years experience in non-related fields. They took samples of each of the pies, put them in a blender, and then tested each sample for colour, lubricity, light transmission, density, ph, and of course percentage of sugar, fat, carbohydrates and fibre. Their conclusion? Within the experimental errors of the measuring devices they were all the same. They gave the blue ribbon to the cheapest pie. 

Not one of the judges tasted any of them. "

Yes @toronto416 anyone with a brain would come to the same conclusion. But there are many flat earthers who believe taste and sound can be measured.

The truth is: ASR does not review anything- they run some tests, meaningless tests, and that is it. 

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.
