Ethernet Cables

I agree with all of the previous responses.

Assuming nothing is defective, and the ethernet link functions reliably, the only conceivable way in which the cable could affect what is heard is by coupling of noise to other parts of the system, including the D/A converter circuit where it might affect jitter, as well as analog circuitry.

You might find this thread to be worth reading, starting at the post at which the link opens. Member Bryoncunningham, in whose sonic perceptions I would have total confidence, reported a significant improvement going from unshielded cat5 or 5e to shielded cat6. The garden variety shielded cat6 he purchased I believe cost him something like one-half of one percent of the price of the top of the line AQ Diamond for a similar length (which, according to the link Mofi provided, would have been $5495 for the approximately 8 meters Bryon required).

Also, you don't say whether the connection from the router to the system is wired or wireless, but if it is wired, and depending on the cable lengths and the physical locations of the components, my instinct would be to be more concerned with the connection from the router to the system than the connection from the BDP-1 to the router.

The bottom line, IMO: If your present ethernet cable(s) are unshielded, and they are located near and/or are physically connected to the system, an upgrade could very well result in significant sonic improvement. But I don't see any reason to expect that the very expensive AQ cables would produce any more improvement than alternatives costing a miniscule fraction of their price.

Interesting discussion. I have an unusual wired setup. The router is in the basement, and I use a Netgear Powerline adaptor to "continue" the wired Internet setup to the LR where my stereo rig is. I plug an Powerline adaptor in the wall near my rig, and run an Ethernet cable from the adaptor to the Bryston BDP-1 digital transport. I have to check whether it is CAT 5, 6 or 7 Ethernet cable. It works fine, whatever it is.

Before I go spending the $$ trying the AQ Ethernet cable, I will try moving up the CAT ladder and see if that makes an audible difference. And if I do go the AQ route, it will have to be from a Seller with a generous return policy.

Thanks to y'all.

I suspect if there were any performance gains to be had via cable choice, gamers would have figured it out long ago.

Someone called? Yep, I'm a "sucka" with $$ to burn.

I replaced generic ethernet cable with AQ and heard a nice improvement. Sound is more coherent and less dark.

Improvements were not as dramatic as going wireless to hard wired or new computer with faster CPU, memory ...

New computer with faster CPU and memory can do more harm than good with Ethernet connection, often producing more electrical noise. Speed doesn't make any difference as long as it is adequate (pretty much any computer) since timing is irrelevant with Ethernet.
