Not to be a snob or anything, but amplified popular music cannot be a live reference IMO. What is the reference in this case? The amps? The mixing board? The speaker stack? In this belief I concur with many others in that unamplified music played in an acoustic space, thanks HP, is the only valid reference for reproduced sound.
Risabet, I agree. I was jsut responding to anothers comments about concerts vs recordings.
My personal reference is solo grand piano.
I grew up in home with a Steinway grand played by a Julliard grad concert pianist. So it's pretty well fixed in my mind
I've never been fooled into thinking there actually was a piano in the room, but the ML's (+the IB sub) are the only speakers to even come close to delviering.
