Tom:
As always, thanks for posting your thoughts. I am pleased to share with everyone that I listened to the 3.7 for the first time the other day. They, according to my dealer, are still breaking in and require 400 hours for the bass driver to fully be at it's best. They are incredible in the midrange. I have never heard, with the possible exception of the 7.2, such lifelike, three demensional soundstaging than these speakers. Jim's new midrange driver technology is the real thing folks and must be experienced to be believed.
The weakest link in the demo system was the amplifier, a BAT solid state example that sounds dull, dry and lifeless to me. BAT's tube amps are another story however! Despite this it was a welcome minor frustration to discover that the sound, like most of Theil's designs, are not "left" or "right". It's just "there" all around you. And that was my immediate reaction upon hearing the speakers whether it was Mozart and especially C.S.N. which sounded so lifelike in the room, I was transfixed.
What was suprising however was the bass response. I am not a bass addicr by any means and the lows weren't weak by any means, just not as loud as I thought it was going to be in connection with the other frequencies. I think break in and system matching are at fault here.
The 7.2, when measured by Stereophile, was slightly elevated in the low bass but I am only too much aware that the sound of any speaker is predicated on what is in front of it along with inherent capabilties.
I still prefer the 7.2. but that could change with greater listening to both. Yet this time around, the new designs midrange driver is truly a technlogical breakthrough.
As you so aptly put it, "I can't wait to hear it with a tube amp". Ditto!
Best:
