Dull sounding amp. Lacks clarity, lacks punch, lacks just about everything.

TA-N55ES just could not drive 4 ohm speakers. Turning the volume up, made the amp shout harshly.

Having experienced some 200 amps and stereo receivers, ever since early '70s.

Big fan, solid 8 due to being able to score this amp for under $125. Mine cleaned up nicely. Seems to either come with or without wood sides, and with either a toroidal transformer or an EI Core transformer. I think the toroidal ones were earlier in the serial # range. I love it, nice form factor and it can go mono.
