[QUOTE="Ampdog, post: 816342, member: 144"] Question: Why is dc input-output circuitry so desirable to some - or desirable [i]at all[/i]? With due respect to folks' preference (and the right to the same), but over all the years I have never seen a good reason for this in audio amplifiers. [Yes it could be done in instrumentation amplifiers; think of all the oscilloscope circuits etc. having that.] But dc signal connection in audio equipment is often a source of more trouble than use. As said, it appears to have more snake-oil/boutique appeal than anything logical. That does not strictly answer your question, simply starting at what should be the first logical question: Why?
