Go Elizabeth!
Actually, at many demos I've been surprised at how loud manufacturers and/or dealers like to play music through their equipment. All music, rock or classical or whatever.
I know Harry Pearson liked to turn up the volume.
I suspect that some dealers don't like to turn up the volume because they're spinning smooth jazz - who'd wanna hear that loud? (Shudder.)
I'm a former choral singer. I've sung in symphonic choirs with orchestras and that produce...well, a LOT of sound. Much more than what you hear out front in tha hall. (It was a trip being in behind the tympani for some pieces, I can tell you.) So I do like to listen to music at "realistic", even visceral levels. But I don't listen that way all the time.
Speaking of loud...
I'll never forget the time at a Pink Floyd concert in the 70s seeing a road manager check (an apparent) faulty speaker. Well, actually, it was a phalanx of speakers, stacks and stacks of 'em, the monsters piled high and wide at the left and right front corners of the stage. The volume was LOUD. During the concert, this guy crawls out across the front of them, from speaker to speaker, making a painfully slow progress whilst the band is in full tilt. After many minutes, he finally arrives at the one he thinks is a problem...balances on his toes and leans the entire upper part of his body into the horn to check it further - blew his hair back! He was in platforms and tight pants too. Wonder what his hearing is like today?
