Thanks for the info wayne, it is much appreciated. My equipment is all tube and is not setup for balanced in/out puts. So I would need the converter box, balanced interconnects, etc. Being a minimalist, the idea of converter boxes and such in the signal path doesn't sound like it would be worth the trouble. I'll wait to find or build a regular "hifi" unit. Most likely, solid state...nuts! Using passive X-O for now,
