Which Solid State Amplifier is Making you Happy?

Jeff Rowland model 8T most musical satisfying amp I ever had. Second in my system with Acoustats the Levinson ML-2's. They do posses such a transparency and pinpoint placement of instruments but they could not properly drive my inefficient speakers. Eighteen Volts was max, but they can deliver lots of current and even drive a Apogee Scintilla 1 Ohm version.
Do not know how well the 8T performs in the lower impedence ranges (I mean 2 Ohm and below). It's specification says only 250 Watts @ 8 Ohm and 400 Watts at 4 Ohm. A perfect Voltage source should deliver 500 Watts at that rating of course. Maybe someone does on this forum?

Brian, specs for the JRDG 8T at:

show a damping factor of 100. This suggests that this amp may not be ideal for driving speakers with very low impedance. If you like as I do the special sound of Jeff Rowland amplifiers, you may have a look at the model 312, JRDG's current flagship. It has a damping factor of 1000 and an output voltage of 125Ohms. Yet, it is to my ears one of the most musical devices I have ever heard. . . plus the usual audiophilic musts of revealing, harmonic complexity, macro/micro dynamics, extension, staging, imaging. You can read a semi-technical sidebar I have just published on this device on the December 2008 issue of The Absolute Sound on page 80, part of my review of the Vienna Mahler speakers. Guido

Stax DMA-X2 Monoblock.

i enjoy my Mac 501's. lots of power and looks like no other.

Spectron Musician III Mk 2. Particularly as monoblocks - so relaxing and "real" sounding that it is a completely different experience for me.
