I build most of my cables for studio and instrument applications these last several years. Well, I generally leave the db25 cables to someone else. Need to look into a testing rig for those.
I shop Markertek and Redco for my cable and terminations. I mostly wind up doing Marketek. Selection is good, price is fair, and service is reasonable.
I do like a Mogami and Neutrix combo for instrument. I like Amphenol plugs, too. They're a bit easier to solder. I add Techflex sleeving sometimes. I like the look and the extra heft. I think it enhances cable durability, too.
Redco custom cables - choose your connectors, wire, length - have been extremely happy with the quality from them. I won't go back to buying other cables.
Yes, definitely awesome cabling. I ended up buying a whack of 1192 from Markertek but I'm less than thrilled with it's performance when used for instrument unbalanced cabling. For mic cables? Absolutely incredible!
But traceaudio made a great suggestion and I'm going to take him up on it soon!
Shameless promoter/evangelist of audioscapeheiserman as they produce the finest enhanced descendants of classic gear available today.
