I’m in trouble

The amp I sold was PA Audio S-300 and Stellar Gainn Cell DAC/pre
it was 140 at 8 and 300 watts at 4 ohms and sounded good when it worked! Amp was not functioning and needed new output brd and re build of trigger on off mechanism. The Pre amp has a chip problem in that the readout was stuck at 44.1 irrespective of input! So I never knew how or what I was listening to- no ability to fix it! Long story -many text messages -
no resolve- so I sold them both!

What I liked about the D class was no heat!
I had Primaluna pre and amp running but living in So Florida listening in a 12’x14’ cave was no fun! The Arcam SA 10 I had fir a test run was rather cool but it did not sound good???
i
may try another one since I liked the amp

I need to keep heat low in my office, so I used these two pieces together for many years

a Carver M-400T amp

Now with small integrated 10wpc tube amp. I still use the Chase unit just for it's switched power outlet for remote system on/off 

What loudspeaker?
