Do Audioquest HDMI cables provide higher quality audio that other HDMI cables?

Any input is greatly appreciated!

Thanks,
Pablo

NO, Monoprice (or 99% of all other HDMI cables) will start with 01100101100 and pass 011001011000 exactly the same.

I hope not...

HDMI audio is transmitted digitally. Just like video, as long as the signal is good enough, the sound will be exactly the same as with any other cable. If the signal isn't good enough, you will hear drop outs or pops. But you will never hear a difference in tone, clarity, "sound stage", or any of the other things that audiophiles worry about.

You got an extra bit in there.

No. Not if they're working. But they have a tendency to be overpriced and not work too well, so...

Thanks for all your input guys! You verified what I believed was true.

Maybe you should consider using a coax cable for audio.

In the Feb 2009 edition of the Hi-fi News magazine Paul Miller measured the following jitter results for a few A/V amplifiers:

Denon AVR-3803A
---------------
SPDIF: 560psec
HDMI: 3700psec

Onkyo TX-NR906
---------------
SPDIF: 470psec
HDMI: 3860psec

Pioneer SC-LX81
---------------
SPDIF: 37psec
HDMI: 50psec

Yamaha RX-V3900
---------------
SPDIF: 183psec
HDMI: 7660psec

Jitter measured where?

What effect does even 8 billionths of a second jitter have on what we hear?

Oh, most profound. Armed with a knowledge that there *IS* a difference, audiophiles all over will start hearing 'tighter bass', 'wider soundstages', 'crisper highs' and 'crunchier middles'. On whatever piece of equipment that costs more $$$. I am not talking double blind, here, of course.

Yes, Yes, YES!!!

The more people buy Audioquest cables, the better quality audio equipment can guys at Audioquest afford.

It's possible that the better sound quality might result from the fact that it probably won't mechanically fail anywhere near as quickly as that Mononucleosis jobbie. After all, any sound is better than no sound

Mechanical failures typically occur from constant movement or hasty installations. Cables just don't mechanically "fail" without intervention of some sort.

FWIW...
I've been using a "Recoton" Toslink cable from 1996 without incident.

Right. Because it makes a world of sense to run a whole other cable that can only provide you lossy audio formats compared to the lossless high-res audio via HDMI, simply because of some inaudible and irrelevant jitter measurements which are anyway made entirely irrelevant if the audio format is DTS-MA or DD-THD because it's going to get uncompressed by the AVR anyway, so any clock problems like jitter are even doubly made completely irrelevant.

Damn, I have the Z7 which uses practically the same design as the 3900 (but supposedly has a lower jitter clock.)

Sounds ok though.
