- We measure and show the results
Alpha NR V2
Typhon T2 (not QR as I said in the video)

You forgot one case: stock power cord into the Typhon.
My exact thoughts, hopefully they'll have a redo!
My thought as well.
Glad you proved it. I have Sigma V2 power cords and they made my system sound better and sound the same every time I listen to it.
This is so great, Mike! Coincidentally, an audio buddy was over just today visiting during lunch, and I played for him the video I put up on YT couple years back also using the same exact Entech powerline noise analyser, and showed him EXACTLY the same results you obtained using Shunyata Research NR power cords & power distributor. And...he was blown away just like everyone else I've done this demo for. Oh, and *LOVE* that DarTZeel CTH-8550 Mk II. Cheers!
Nice demo! BR
Can we see the brands that don't do anything?
Hahahaha.

Evening from tropical Scotland 😁 I hope everyone is safe and well 😁 so what happens if you use a stock power chord into the typhon ? Just thought I'd ask ? Please stay safe and see you at axpona 😁
Great video Mike!
Question, a lot of these high-end amps and preamps, how come they don't include a good power cord if they want you to use it with that piece of equipment?
Because Everyone has their favorite
As a few folks intimated, this really doesn't show much. Not that the test is flawed or that the presenters are hiding anything it's just that;
1) The analyzer is a "black box" with no definition of what it is analyzing. What does it consider noise? Induced FM signal would certainly be noise, but probably does not impact the audible spectrum.
2) The last test should have had another power cable between the conditioner & analyzer which would be required from the conditioner to the equipment being powered.
3) If the noise is in the audible spectrum, what is its amplitude in either watts or DB? If it is less than "N" DB, it would be inaudible to even a dog. All the test showed was a percentage, if the base line noise (100%) is 2 DB reducing the noise to 0% is meaningless.
4) The filters built into all power supplies in electronic equipment are there to filter out noise. How much do they reduce the noise?
I suppose a test which MIGHT make sense would be to put a scope on the power rail of a piece of moderately priced equipment and measure the noise in absolute values in the 3 situations provided.
For additional fun feed a pure sine wave signal at a relatively low frequency through a preamp & amplifier into a non inductive load. With a dual scope, connected to the input of the preamp and output of the amplifier, show what the signals looks like in the three scenarios. This last test MIGHT actually show if there is any difference which could potentially be audible.
Should do the other way around. First plug into the typhoon and adjust the sensitivity to the level where we can hear some noise (with shinyata cable OR standard), THEN measure the shinyata cable alone, THEN the standard cable... PLease try it again !
Are any of the differences audible?
Yes, but you’ll never convince the meter readers to trust our ears.
Most of this stuff that's measured cant be heard, thus snake oil
You guys are really misguided and clueless
How so? Now you don’t believe the measurements?
@@highendaudioIt's useless and meaningless. Has nothing to do with any sound improvements. It's all nonsense . Hook up real test equipment, like an audio precision unit...not that goofy wannabe box thing
@@cengeb sure! Bring yours over
The power supply inside the unit (amp, preamp, whatever) will filter out this noise. Hilarious BS.
My powersupply bla bla bla…
Nope! In point of fact, the full-wave bridge rectifers in the power supplies inside amps, preamps, etc. are one of the *biggest* contributors of noise in a system.
They could have add some magic grounding box and come up with -100% :)))) No need for anything - hook up straight to the speakers...
I worked for a metals company that still used old IBM mainframes, the power going to these was very important.
