Excellent sound quality. The perfect replacement amplifier for devices that require a single ended amplifier setup. I used this amplifier to replace the dead one in my IMA/Craig PS-A2500 stereo entertainment system and wow the sound quality totally destroys the old one. You will need to make sure to use a good heat sink, also, I would highly recommend getting mica based transistor insulators. They may be old-school but they draw away heat from the transistor much better than the supplied ones.
Everything is OK. It will only be assembled and tested during the holidays. Extremely fast delivery.
