My 2 cents:
In 1972, my band, One Nite Stand (I was going for "cheap trick" but did not think of it) was playing in Bristol (VA/TENN) at a college music fest. We were "second" to another band called The Allman Brothers Band. (We played a set, they played a set, etc.)
Naturally, we knew who they were, but they only had two albums out at that time and were basically popular regionally. Anyway, we are sitting in our motel room at the Holiday Inn around 4:00 PM with the door open and a guy with long, blonde hair walks by. Back then, anyone who had long hair was considered a "hippie" and disdained by people in small towns like this, to say the least.
We looked at each other and someone said, "Hey, I think that’s Barry Oakley from the Allman Brothers." I walked out and called, "Hey, man." He stopped, we introduced ourselves to each other, and he invited us up to their room (fellow "longhairs."). Needless to say for a bunch of 20-year-old college guys, we were thrilled. We went up to their room and met them. Our lead guitar player, David, was talking to Duane and after a while asked him, "So, man, what was it like to play with Clapton?" (Clapton had just recorded and released "Layla," and since Clapton could not play slide as well as Duane, he asked him to come to England and play that part on the record.) SO, back to the conversation:
DAVID: "Hey, man, what was it like to play with Clapton?"
DUANE: "Well, man, how did it sound?"
Kind of like my take on systems today. Measurements are nice, but, as Duane asked, "How (does) it SOUND?"
In my shop, which I opened a few years later, Magneplaner’s hooked to Audio Research gear SOUNDED the most realistic. The measurements were interesting, but to me, and many of our customers, we wanted the reproduced music to sound most like it did when we played it live. This was the combo that accomplished that goal.
Lots more to the story--watching Duane and Dickey play while standing on the side of the stage after our set was an experience I will never forget. They were "in the zone" and suffice it to say, it was magic.
So, as I asked my customers, "How does it SOUND to you?"
Cheers!
