Mogami 2549 (Standard) vs 2534 (Quad) etc

I use Mogami Gold and have them made at 

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.
