Well, someone should have a listen to them and report.

In the meantime, this is interesting...

Please excuse me if I don't debate the merrits of a product.

There will ALLWAYS be some one claiming to make one better, and some claiming its junk.

EVERYTHING in audio is PERSONAL preference. NO rights or wrongs.

If the device works and YOU like it then it is good. There may be better, there may be worse, but if it's yours and YOU like it, that’s all that matters.

No I don't own any AudioQuest products but I really liked the old Midnight cables... I used a friends set in my system and liked them in mine and his...

Hey rabstg,

You are absolutely correct.

The problem with reviewing new cables, especially apparently technologically advanced, good looking, and/or expensive ones, is to judge with your ears and not get caught up in the hype.

I find a healthy level of skepticism is a good foil for the hype.

The audioholics approach is good, they're interested in scientific analysis, but are not completely ignorant of the possibility that a cable may sound different in spite or because of it's construction and cost. It's a pity Audioquest did not take them up on the offer of a blind comparison against zip cord:

"Alternatively we can arrange a controlled DBT with your cables and say 10AWG Zip Cord with a panel of listeners and do a statistical analysis to determine correlation that your cables really do sound "better" and that your reasoning is sound. We are willing to work with you on exposing the truths about your claims to promote better understanding for our readership and the rest of the audio community. Here is your chance to educate the public about a science that is allegedly not well understood and have an independent source peer review and confirm."

That's from this page

Regards,

Michael

Wow, after reading some books, i know that cable has important role to deliver sound. Material and cable's geometry are important. Choose the best dielectric insulation and size of the core.And there are many cable geometry, such as parallel, twisted, coax,twisted with dielectric in the middle.
Cable can cause many effect like skin effect.

Absolutly!.. But usually NOT at HUMAN audio frequencies..

In the wide band sense cable is a band pass device.

Oh, i see, so the cables don't have much effect which audible for us.
But, i think the geometry of the cable is important (twisting technique).
Here is my GC with a Microphone cable:

I use microphone cable as internal wiring to avoid EMI because i use EL trafos.
And now , i still think to build a buffer with mosfet output for my 3886GC like sijosae multihybrid amp which use 6922+IRF.
Maybe by add a buffer can improve my GC than changing a cable

I do think cable is important. I'm using 2 pairs of
Cat-5 bcables on the input and 6 conductors from
the output of the chip to the speaker terminal. I'm using
8 chips per amplifier so I'm using a total of 48 Belden
1585A strands for the signal.

In my opinion the effect of all cables can be heard. I once
measured the capacitance of my HomeGrownAudio
interconnect cable to be about 10pF while a high quality Partsexpress cable had a capacitance of 400pF. Depending
on the choice of impedance these effects may become audible.

I do not understand the effect but I always hear the
breaking in effects. It takes 50-100 hours for a new
amp, wires etc to give optimal resolution.

I never use stranded wire anymore. This is after I bought
some silver plated stranded copper speaker wire. This is
one of the worst cables I've tried. This is not to say that
this is true for any stranded cable but I'm no longer
taking that risk.

Sorry but upon re-reading I have to clarify...

"But usually NOT at HUMAN audio frequencies" was a comment on skin effect only. Cables MOST certainly affect other characteristics IN the audible spectrum, just skin effect is not one of them. Skin effect usually does not become a factor until the Mhz range, and ARE the way signals are carried in the Ghz range in some systems.. Microwave, Satellite and radar to name a few.
