I find the tests you do very interesting and your efforts are much appreciated! I must confess I am studying the results of your videos and it is not like work for me. .
Not watched the whole video just yet (1:01:22 in so far) so not sure if you covered this later on, but the Puritan PSM136 and more expensive PSM156 you were using both have very effective DC blocking already built in to them (as well as their various levels of filtering for common and differential mode noise). Thought I’d mention this in case it’s of use for anyone 👍. [EDIT - I see you did pick up on the built in DC blocking - but query if the unit you have has been burnt in, as they particularly warn customers to burn in for min of 100 hours before it realises its full potential. Maybe it opens up and is less “rounded” after? Also everyone who’s tried says their upgraded Puritan power cable to the unit, instead of their standard one makes a huge improvement. Just thought I’d add this]
Am just happy I learn more and more what my taste is in sound. If you have time to explain why you like about Mammal Hands -- Captured Spirits - Spiral Stair and at what point in the track you listen specifically too.
Two things: 1. You either like a certain piece of music or not. That's irrespective of the audio quality in recording or playback, it is music. I like this music. 2. Some recordings are better suited for auditioning equipment than others. From those recordings, a few really work to get the differences we hear across to the listeners at home. We do not listen for something specifically, it is about the tonal balance, the colour of the instruments, the rhythm, if things fall out of place in terms of rhythm, harshness of sounds. We listen how the soundstage is placed, how clearly instruments are positioned in the soundstage. We listen how easy it is to follow what the different musicians are doing. So, it is not a particular thing. And all of us are zooming in on different aspects by default, because our ears are all sensitive to other areas. That's true for every human being.
@@Burphy42 For the written reviews we do we have different recordings. My tests lists are published on Qobuz and I refer to them in reviews I write. Live-streaming is a different ball game.
For a ridiculous $200, some of these power conditioner companies also sell the exact same hospital grade wall receptacles which you can buy at a home repair store for $15. That makes me lose faith in these company's integrity and honesty. You should try this listening test with a few different brands of cheap $30 surge strips. Each of those would probably sound different too.

Good stuff! I just happened to get me a PSM156 and was very surprised how much it improved the sound of my system (stage width, depth, spacial cues, etc.) However, in the first day it sort of tamed the transients a little, which I was not too happy about. By day 3 it “opened up” so no transient masking, huge dynamics and just wonderful sound. So yeah, it definitely needs burn-in time.
Another great video guys. Too bad that it didn't happen last year when I purchased a Furman power distributor... The Supra would have been a better choice or the Isotek Gemini, which I was looking into by the way. What was the Furman model that you Jaap tried and didn't like? On the outlet polarity, i have a question, correct me if I am wrong because I am just learning about this, but if the polarity was reversed, to bring it back to normal, the wiring between the hot and neutral lines needed to be switched in the outlet, but you did it very fast there in the video, so how was it corrected? Thanks again and keep up the good work. just editing my comment here. The polarity issue is more of a problem in Europe compared to the US/Canada/Latam region, as our outlets have three prongs, one for grounding. So you only have to rotate the plug 180 degrees to solve the problem. Although the problem of having wrong wiring connections on the outlet affects everybody. Actually, in Europe the problem can be solved a lot easier.
I've had a lot of questions about these things, and these models in particular. Thanks for finally bringing clarity to the subject. Very good video, indeed!
A huge thanks to the team for this super fun and illuminating test! I appreciate the work and time commitment involved and I hope these will continue - I for one look forward to these sessions, and the way they are presented makes us feel a part of the the group. I have the PSM156 feeding my power and pre and it was journey of burn-in; beginning slightly harsh, quickly settling to become warm but rolled-off, and then (after about 2-3 weeks) becoming more detailed, spacious and balanced (did it change or did I? 😅). I think your conclusions and guidance are 100% - try before you buy, and check to see if the manufacturers also offer the option of 30 day return.

yes great and entertaining review! by the way is it normal that you can shock yourself with a SNS plug like Jaap experienced? seems not okay. I believe SNP plugs have a CE certification so wondering...
Great! I moved from the city (apartment complexes) to villa area with lots of wall box chargers and solar panels around, including some on my own roof. DC was MUCH worse in the city, to the point where I could not block it properly with any of the Supra DC blockers. Out here the blocker works well.
...and I have been listening to the AudioQuest Niagra 1200 and it certainly *seems* the better sound is from the low power plugs. Much better. Your livestream gave me the idea to try it out.
Good thing about Aussie mains plugs is they can only fit one direction so polarity is always correct. They have two flat prongs for the active and neutral angled inwards 45º at the top.
hey guys.. thanks for the work .. fun to watch, entertaining, ..(although maybe next time test it with streamers/DACs/amps of the 2020s.. ;-)) I am thinking of upgrading my power supplies.. so one question, one comment: which power filtering system/ conditioner or whatever to use for devices with switch mode power supplies?? ( I own a decent Linn streamer/DAC ) ... how about power regenerators i.e. ps audio.. that ok for switch mode device + torroidal in one system ?? .. you know, its hard for normal customers to test this amount of devices at home and only keep the best one for your system...

We don't have this phase issue in the UK I think, as our plug architecture stops this. I have a separate dedicated fuse box feeding just the hifi equipment and this helps lower noise interference from household items.
Not necessarily. If the electrician wired the socket not according to code or if the power strip reverses phase or the audio equipment is wired differently, then it can still be wrong. And more difficult to resolve as you can't just reverse the plug.
They needed to use a ultimate cable with the puritan to be honest. They said it was too smooth.... that's absolutely the stock power cord that came with it...

@@Coneman3 Reverse them in the chain and listen to the result. Most of the time, audio enthusiast go way too far by stacking tweak upon tweak upon tweak. The end result is invariably the same: music starts to sound sterile and the enthousiast listening still feels that vague notion of dissatisfaction -- and invariably starts to add more. How to know when enough is enough? I do the following: take everything out of the chain and start with a sources-amplifiers set directly connected. Maybe a standard power block. Listen to it for two weeks. Then add whatever you have gathered over the years one by one and listen critically: is the music _really_ sounding better? I can tell you I have removed a lot over the years.

@@totalplonker824Totally plonkers!
Thank you for another revealing test! It is makes any sense to use DC blocker prior to power conditioner?
Yes, if you have a DC problem and if the power conditioner doesn't address DC. Watch the segment about the Audioquest.
I use them after power conditioner and it gives further benefits. When do you know enough is enough?
@@Coneman3 Reverse them in the chain and listen to the result. Most of the time, audio enthusiast go way too far by stacking tweak upon tweak upon tweak. The end result is invariably the same: music starts to sound sterile and the enthousiast listening still feels that vague notion of dissatisfaction -- and invariably starts to add more.
How to know when enough is enough? I do the following: take everything out of the chain and start with a sources-amplifiers set directly connected. Maybe a standard power block. Listen to it for two weeks. Then add whatever you have gathered over the years one by one and listen critically: is the music _really_ sounding better? I can tell you I have removed a lot over the years.
amazing video you should do a separated short video with the highlights and conclusions, 2 hours is too long and interesting information is lost in the sea of time 😅
There's always a written summary on the website after each livestream, in a few days.
@@jmtennapel good to know thanks!
