Bottom Line: Much better than Jeff Rowland model 10, which I used before.
A perfect match for the new Thiel CS 3.7!

Bottom Line: Before buying this amp, I was using an Audio Research LS17 with a VT60 tube amp driving a pair of vintage Klipschorns (Bob Crites tweeters and woofers plus his capacitor kits). WONDERFUL sound!! The only problem is the lack of bass using a tube amp. I found a demo Usher r1.5 amp on Audiogon for half price. The sound of this amp is as good as the tube amp, but with WORLDS of clean, tight, well defined bass.The detail and soundstage coming out of this combination is unbelievable for the price. After listening for a few months, I would have no problem paying full retail price for another one of these amps. I don't think you could buy a better amp for twice the new price of $2500!

Strengths: Very dynamic
Very controlled
Very detailed
Very very well built (All aluminium, 32x250 watt motorola transistors, weight 37kg)
The best loudspeaker terminals i ever have seen on any amplifier/loudspeakers!
Weaknesses: My amplifer has balanced inputs, but they are not connected internally in the amp!
Generates a lot of heat. (200 watt idle power consumption.)
When switched off, the amplifier still draws 85 watt.
I think an amplifier of this class, should have more capacitator capacity than 40.000 microfarads.
Regarding the sound, not much!Bottom Line: I bought this amp to use it with my Martin Logan Aeon I loudspeakers. The R1.5 performs this task very well. The sound is dynamic, clear and controlled over the entire frequeny range, when driven moderatly. At very high power levels, it seems to loose control gradually. My speaker have a minimum impedance of 1 ohm at 20kHz, so I guess with loudspeakers having a more linear impedance, the problem woud be less. I have not tested it with other speakers, and i have only used the unbalanced inputs.
Price Paid:
$2900.00
