Mogami 2549 (Standard) vs 2534 (Quad) etc

You can purchase whatever length XLR or rca terminated Mogami Gold cable you need at Amazon.

I have also had them made by the folks at Blue Jeans Cable.

 I prefer Van Damme Classic XKE  

​​​​If you google it, a gearfab post claims 2549 sounds better.

Just based on the docs, the quad has better noise reduction.  Not likely to be an issue in most homes unless you have long runs or are near strong RFI sources, like a radio transmitter or machinery.

Having said this, I prefer the pure silver DH labs.  Brittle but I've gotten rid of everything else.

I have cables made with W2549 and others with W2534. Both pair have the same Neutrik connectors; both are 25 ft long.

Five years ago, when my HF hearing was better, I thought that sound through the ordinary mic cable (W2549) had SLIGHTLY more HF response. Maybe.

I'd use W2549 for most applications. If in an area with extreme RFI, the W2534 quad cable, which has better interference rejection, would be better. But for ordinary applications, even running a line-level audio cable near a power cord, there is no need for a quad cable.
