An industry guy came by this weekend and they did a shootout with some crazy expensive power cords (something like $8000-10,000) they both agreed that our B24 was better.

The problem with the demo that was run was that the power cable you're referring was that it was not a properly controlled experiment. The cable you're referring to had just been transported in a motor vehicle from Utah and did not have sufficient time to settle. Vibration from transporting a power cable in a vehicle induces triboelectric noise into the dieletric, which impacts the cable performance and the impact of this is quite audible.  Further, one cannot determine which PC is better simply doing a quick "A/B" swap. In order to do a proper comparison between  power cords there needs to allow sufficient time for the power cord to fully settle fully, which takes 48-72 hours. If one is going to do an A/B comparison, the demo needs to be set up in a scientifically controlled manner with two identical systems so that one can compare the use of the two different power cords as the only difference between the two system, without, and this is the key point, one power cable having to be swapped out for the other. Otherwise, if one power cord is swapped out for the other, more vibration is being put into the power cord being installed, and it will again require time to fully settle.

I'm just reporting what I was told by Danny.  :P
I was busy working in the shop cleaning, answering emails and duratexing woofers while those comparisons were happening.

So I can't say for certain if you're right or not, and that's fine, I'm not one to argue.
I'm just learning as I go, tbh. :thumb:

No worries. My only aim here is to convey maximally accurate information so that potential buyers can make informed decisions about what constitutes value propositions when it comes to products like power cables.

My personal view is if folks are interested in considering power cables from Danny, they should go ahead and buy them; as they represent an excellent value for money. From my >10 year experience with audio-grade power cables, in my view, they are the single most important cable in a stereo system.

Read this: https://www.gcaudio.com/tips-tricks/why-power-cables-make-a-difference/

I appreciate this.  I read it.  I'm still somewhat skeptical as I think the placebo effect is more powerful than anything else, but I will be trying some different power cables on my mixing console when I go back out on tour in September.  If they actually work then a $100k mixing console with 96 inputs, 24 outputs, running at 96k/24 bit sampling will show me the difference.  I'm open to it.  I will test them with several top audio engineers in the live concert business and see what they hear.

Report back in 10 more years and you'll have two things -- 20 years of experience and a different opinion.

Nope...10 years experience tells me what I need to know. The physics of why they matter won't have changed, either.

Cool. Let us know what you find out.

BTW, If you know mastering engineers Rick Rubin, Peter McGrath, Vlado Meller of Sony Music, USA, or Clayton Wood of Skywalker sound, by any chance, ask 'em what they think of audio-grade power cables.

Cheers.

I will report back.  FYI- I am a live sound engineer and don't know those guys, but I am around studios from time to time and I will see if anybody is using them.  I have never noticed it or asked and most live engineers I know will think that it's crazy to use expensive power cables, but I also don't know any of them who have tried it.

Only 10 years???? You're just getting started. Read this thread: https://www.audiocircle.com/index.php?topic=170477.0

Some of the guys (and a gal) on this forum began their audiophile journey in the 60's and 70's.

Here is Michael Rhodes on cables for bass players:

Bernie Grundman has been using custom cabling to custom power supplies for years.

Bob Clearmountain

Sterling Sound

Also, ask these guys:

Dave Gilmore's Astoria recording studio. Michael Zimmerling (recording engineer for Simply Red) and recording engineer/producer Ken Nelson (Gomez, Coldplay).

And Russ Andrews - Hi-Fi mains and cable specialist

And then there is Alan Parsons and a few other Brits that are squeaking all they can out of idiots gear in the studios.  Oh, and Tim de Paravincini (RIP) and...

I started in 1976, just out of University, so I am definitely not a newbie.

Specifically, I've been enjoying the benefits of audio-grade power cords since 2009. Danny is 100% correct, they bring a notable improvement in audio systems. His power cords are well-designed, well-manufactured and affordable, so they are quite a good value proposition. Folks can try them in their systems and hear the improvements for themselves.  :thumb:

They will also demonstrably improve the quality of video in home theatre systems, too.

Exactamundo. I was going to reference Astoria Studios but was not sure if folks in the USA knew of them. Also Phil Taylor and Andy Jackson, also at Astoria, use aftermarket PCs specifically designed for audio applications. Sony Music Japan does, too.

I dug through my records and listed a few more, too.  The guys at the top get it.

I forgot Peter Gabriel's Real World, too.

There is Jan Lusczczek at Clair Brothers that swears by console cable upgrades.

In months of hanging out on this forum I've never once come across someone who has been anything other than helpful and friendly. Personally, I really enjoy that atmosphere and don't want to sully it by going down a different avenue - but it sure is tempting.

Oh, yeah...they wouldn't be the top if they didn't. Just like Danny, they're the real deal, and know what's what.

Concerning Subsonic's comment about power conditioner's internal wiring being "anemic".  Are you talking about wiring to each receptacle or outlet?  If so, you need to consider the aggregate total.  i.e - 4 x 14ga wires is an aggregate of 8ga.  It will take an 8ga cable to provide the total current handling of the receptacles or outlets.

Also, chassis wiring current ratings are different than power transmission.  14ga wire is rated for 32A in chassis wiring applications.  The 14ga wire used in house wiring for 15A circuits is only rated at 5.9A for power transmission.  It is all about average current demands.  Appearances can be deceiving.

Bingo. Good post. Accurate.  :thumb:

The Vienna Philharmonic uses them too, for mastering their classical recordings, as well as Steve Epstein, who has won 6 Grammys for classical recordings.

And then there's Doug Sax and James Guthrie. So,...yeah.

That would be assuming that every device plugged into the line conditioner would be drawing the same amount of power. You could easily have 2 powerful amps plugged into one receptacle while you have extremely low power devices (DAC, streamer, turntable, etc) plugged into other receptacles.
