I'm selling my Krell KSA-100. This is a classic class A amp. I've been using it over the last two years to power my Martin Logan Request, which I just sold. I'm moving to a smaller apartment and don't have room for big audio any longer. The amp works great except the fans went out on me about 7 months ago. I've been using a fan on top of the amp to keep it cool and haven't had any issue. Rating this amp a 6/10 due to the fans. I’m pricing it fair since the fans need to be checked. Please contact me with any questions. Pickup only because this thing weights a ton!
