Our room was quite large, and we filled it with music that was musical, well-controlled [except for a little bass overhang around 100 hz and a room resonance freq around 500? hz], smooth, harmonically rich and etc. etc.
It invited comparisons with a ‘live’ performance [not talking here about the overly simplistic demos that are primarily percussion and electric guitar we see out there sometimes]. Wasn’t quite THAT good, but, for me, this is what high-end audio is all about.
Convincingly live music in my room at a push of a button by any artist from any decade.
