+1 on the Virtue One (or One.2). I have used both the One and the Sensation in a near field arrangement using a computer as the source. Even with the stock power supply (24v/65w), the virtue amps put out 30+ watts per channel, and they can drive any speaker load from 2 to 16 ohms. I still have both of mine, they beat any other tube or transistor amp, even at many times their cost. You have the option to upgrade the power supply to one more powerful, or even something high current like a linear supply or batteries, and these amp will sound even sweeter and more powerful. Plus they have that magic Tripath sound, very tube-like, but with power in the low end and no rolled-off highs. Yeah, I'm a fan...
