In lieu of building a guitar amp isolation cabinet I was thinking of putting the amp in another room that has pretty good isolation. (Specifically a well isolated wine cellar. Not sure how the music will affect the wine.) This would entail a pretty long cable run. (It's only about 20' as the crow flies, but there ain't no crows flyin' that way.) I'm reluctant to do this with high impedance TS instrument cable. My first thought is to use a pair of passive DIs so that most of the distance is covered by an XLR cable. Is this the standard way to do this? I've never used a DI with the XLR as the input and the TS used as the output, but I don't see why it couldn't be used this way.
