This is my best amp to date that I have owned. There is no heat issues with my model at all and works and sounds incredible. For $250 CDN this amp was my best purchase and makes a great entry level amp. Built like a tank too and is not as heavy as my Harman Kardon Citation 19 but it performs like a charm you will not be disappointed if you find one, try it out...it is similar in sound and somewhat power to my Nikko 130 which also operates cool.

Picked this up broken and repaired it. Easy job to fix, very modular and everything is robust. Large dual transformers, 20,000uF a channel, and huge heatsinks on the back.
I give this a 8 because it sounds amazing and is durable, but it has some thermal issues with the vbe multiplier, and the driver transistors are not very high quality. The VU meters are beautiful. Wonderful amp to have.
