Balanced XLR cables

+1 on PM'ing Ralph. You can also call him (phone number on Atmasphere website). If you don't get him, you'll get one of his able assistants.
@OP,
I bought a long run (25 ft.) from Ralph, when I bought his amps.
I was encouraged by my dealer (a very knowledgable fellow), to buy some AQ XLR's, as he felt it would be an improvement.
To my ears, there wasn't much difference.
{I think Ralph uses Mogami, but I am not sure. In any case, I would buy the cables from Ralph}.And, they probably won't cost $50 for 3ft lengths.- And, at such short distances, I doubt you'd be able to hear any differences between manufactors.
Ralph can elucidate more than I, but when equipment utilizes AES 47 standards, the effect of cables (soundwise), is minimized. Which is probably why recording studios use them.

Just because you have balance inputs and outputs does not mean you have a balanced system. If your gear is truly balanced from input to out put, then yes a good balance cable can sound better.

Mogami quad cables are balanced only ruined by how you wire them.

You can get (balanced) cables made to order, using Mogami W2549 and gold Neutrik XLRs, by many pro audio shops. This is NOT expensive, certainly not by audiophile standards. I have had very good service from ProAudioLA.

Because of the length of interconnects in my system (25 ft), it’s been difficult to compare to many other cables. Another Mogami cable (W2534) and Gotham GAC-4/1 sounded very similar to W2549, with W2549 the most open by just a hair. A well-known audiophile brand costing 15x as much was superior in no way and was noticeably colored in the treble.
