The Mains Chance

A friend who owns a music business retailing musical instruments, mixers, etc and who rents & installs gear at concert venues thinks all audiophile tweaks are a form of insanity. He's sent me a cutting from March 2010 Hi-Fi news (www.hifinews.co.uk) which I've copied here as I think it sheds some light on a topic that's puzzled a lot of us for some time.
So, hoping I'm not breaking copyright law, I'll past the whole thing here for comment.
The Mains Chance
Can your choice of mains cable help reduce unwanted mains-born noise. Jim Lesurf decides totake a look using good old-fashioned engineering ideas. So
What

Re: The Mains Chance

I wonder why this dude is only occupied with interference in referring to different power cables. IMO there's a great deal of improvement in the soundstage, the background silence, the transients etc as well. I also don't think people generally buy new power cables to fight interference, but to get more "oomph" from the system.

Thats what I thought. Isn't that the reason why we have dedicated lines ran to our systems. To ELIMINATE interference?

My set up: Two dedicated lines. From service panel to wall outlets is 11 feet. 10 guage romex married up to Levitron 20 amp hospital grade outlets. No inteference. Mega-Huge improvement in background silence. No transients except for when I am utilizing my Adcom GFA-555 amp and I turn it off after listening. I get that speaker 'pop' after the caps discharge which is not even a power cord issue anyway. My Levinson amp does not do that.

Re: The Mains Chance

WA? No golden eared listening test?????

This guy has written about mains cable and amplifiers on the basis of electrical (RF?) performance! Why bother posting such objective material here? To qualify, the tester needs to report on the "ASTOUNDING!!!!!!" improvement when using the Dodecahedral Pure Reference Shiraz Mountebanks Everest mains cable (cheap at only a bazillion dollars). The soundstage! the detail! the lack of cuppiness! there was a whole choir of chipmunks in that arrangement that I had never heard before!
All this talk of electrical properties won't do at all...

Cable debates can be the most tedious of all audio discussions as they so often fall into the black / white, either/or type with posters taking up sides as if they're supporting their favorite football team. My perspective is one that respects empirical science yet submits that not all some of us on some systems can hear can be measured. And yes, there's more obscenely overpriced snake oil for sale out there than makes sense but that doesn't mean you can't be surprised by something as simple and cheap as the solid core silver speaker cables I just knitted up myself that have, to my ears, added an extra layer of joy to my music.
So, if someone was to measure why they work so well I'd be happy to read their results but that's not going to increase my enjoyment just because I know why they work so well. Does that make sense?

Well so far no one has other than the measurable LCR components of wire but then again Stereophile doesn't bother measuring ANY power cord, cable or magic bowls because that would mean making an EFFORT plus it just might show either an outright frequency response change OR NOTHING at all going on and we all know how that might cut into add revenue

Got any graphs, charts or measurements to show proving your power cord does ANYTHING other than deliver AC from the wall outlet to your audio component? Thought not. Oh yes I forgot you have 40 years of "experience" in your favour "I know what I hear!" yeah right.

David_L, what interconnects do you use?

What gear?

Who are you asking? If me - my interconnects are all home made thin, solid core silver, plaited with a third 'drain wire' connected to earth. Only the cartridge to phono pre-amp is shielded. Balanced connections are joined to 'Vampire' XLR plugs, un-balanced to Eichmann plugs.
My main music only system is as follows:-
V.P.I Synchronous Drive System: V.P.I. HRX turntable: JMW 12.4 arm wands x 3 ( cartridges pre-mounted) resting on heavy slate on top of Soundesign damped steel rack standing on a stone floor: Garrot

Your right Keld.
The mistake I believe that David_L makes is one of not taking in to consideration that no two people have the same identical sets of ears. We are all different. So, with that said, What one man can't hear... the other man can hear. It's not impossible.

...just my two cents.

And a valid two cents worth. It's why I've always believed audio reviewers should publish the results of their clinical hearing tests along with the response curves and square waves of the junk they're reviewing. Won't happen though.

Never in a thousand years will it happen because that would cut into the advertising profit when it showed that it's all bogus

DM, You hit the nail on the head. Reviewers taking hearing tests. That's the kind of truth advertising we all could appreciate and benefit from. But your right, it would never happen

I demand to see all y'all's hearing tests to make sure Stereophile's pearls are not falling before potentially deaf swine.

I also insist you shop based on how your teenage daughters think your gear should sound.

Happy?

LMAO! good one buddah. My right ear, I can hear a whisper in Times Square at noon. On the other hand, my left ear, I couldn't hear a church gong if I were in the bell tower.

After 21 years of sitting in the back cab of a fire truck for 21 years, my left ear has taken a beating from the siren.

as far as my 11 year old daughter...it would be Hannah Montana 24/7.

So, you should use right-sided speakers on both sides of your room to get around that issue.

How many years did you say say?

Now, does your hearing render your audio opinions inavlid?

I say it does not!

Me too but it does draw attention yet again to the idiotic exclusion of inter-channel balance controls on so called high end amplifiers.
If purist audio designers are so terrified of balance controls surely they can give us defeatable ones?

Interesting analysis Buddah. Right sided speakers..I think that may work

Man! I just had an epiphany..No wonder my politics lean to the right...I only can hear one side of the argument maybe my political stance should be rendered invalid eh?

My daughter is 11. Well actually she will be 11 on Wednesday. She wanted one of those little camcorders from Wal-mart called a "Flip". She is already becoming a little techie Sheesh! Im going to go broke. lol!

I gotta pic of her in my gallery on here if you are so inclined.
