Analog Research Technology

With its thick milled Aluminum front face plate, it was clearly one of the best looking amps of the bunch.

It had balanced and unbalanced inputs that looked like Cardas. Speaker binding post were clearly Cardas reference. These were among the nicest of the group too, but they do not take banana plugs.

I believe this one was a ICE module based amp but I think I also heard mention of some option Hypex based amps being available too.

The only objective thing that I didn't like about this amp was that the power switch was on the back of the amp and I don't like feeling around on the back side of it trying to find the on/off switch. A power on light in the front would be nice too, so that one would know if it were left on or not.
