My approximately 20 year old Classe CA-100 amp has stopped working (goes into protection mode upon power up) and I'm thinking that its going to be pretty hard to get it fixed given it's age. Problem is I've kind of lost touch with the current gear. The CA-100 was a great piece and we really loved the sound so I want something with similar performance capabilities. We are driving Revel F32 speakers and using Classe CP 45 preamp, NAD optical drive C516bee, and Bryston BDA 2 DAC all connected with assorted Transparent interconnects. These are the amp specs:

CA-100 SPECIFICATIONS:
Frequency Response: 20 Hz to 20 KHz - 0.1 dB
Sensitivity: 950 mV in for rated output
Input Impedance: 75 Kohms
Output Impedance: 0.036 Ohm
Gain: 29.02 dB
THD+N: 0.030%
S/N Ratio: 128 dB
Rated output: Stereo Mono
8 Ohms: 100 350 Watts
4 Ohms: 200 600 Watts

I would appreciate any input as to what to start looking at to replace this piece and any opinions on whether and integrated amp might be a better option since the CP-45 is the same age as the amp. I've set a target range of around $2,000 US.

Thanks

Thanks
