I'm using Pro Co Excalibur cables currently, which are 20'. I'm wanting to cut down on excessive cable length to ensure the highest quality recordings as possible on my home studio budget. 1) Including the patch cable, and entire routing, what total cable length should I be shooting for, with an unbalanced cable? 2) Would anything under, say, 20' not pose any potential problems? (i.e. would most, if not all, of my signal/decibels still be present) 3) If I chose to use balanced cables, with a mix of balanced and unbalanced gear, would I expect to get longer cable runs with less signal degradation or would it be about the same?
