Current speakers are Michael Green Audio Rev80i free resonance design. Let's say their sound signature is close enough to Grado RS-1 wooden headphones. I play at moderate levels, many kinds of music but not hard rock or big orchestras.
I don't tolerate bright or "stupid" hi-fi kind of sound. Midrange must be right or I won't listen. Going down confidently to 35 hz would be enough. Soundstage is very important, the space should be "heard" and felt.
