re: Obelisk 100

I agree with michael habla. This amp is a big problem for bias control and stability. Thermal problems. Easy to oscillate. In case of faulty it damage the speakers. Power transformer too small, it turn to high temperature during listen. Bridge circuit like the most cheap car stereo amplifiers.

Very very problematic.

re: Obelisk 100

poor thermal feedback for bias control, easily gets knocked out.
bridge output circuitry questionable.
120 va torodial transformer makes poutput power specs questionable.
poor and instable design, sorry to say.
