I've only spent a few hours with it but I have to say it is everything Zero said it was. It is much like the Sonic Impact T-amp in that it distorts differently than other types of SS amps. It may not have as wide of a soundstage as the SI amp. Certainly at 30 wpc it has a lot more force than the SI. This has to be about the cheapest intro into audiophiledom there is... Actually, if you have eff speakers I would recommend the SI but if not the Teac has enough power for less eff speakers.
