Has anyone looked at a schematic for a line stage that has two set of outputs? My suspicion is that both sets are simply wired together in parallel internal to the amp. The second set of connectors is very convenient on the amp but is this really any different (better) than using a solid block Y-connector on a single set of outputs?
Or, you can save a lot of $$$ on cables by putting the solid block Y-connector at the amp and using a short 1/2m jumper to the other channel of the amp. This, of course, is applicable for vertical bi-amping...
This is bit more complicated (and maybe not possible) if balanced XLR is a requirement.
