used power amp under 1500

The Threshold 400a was produced in 1977 - 1979. Basically one of Nelson Pass’s first designs. Make sure it has been reconditioned. The capacitors nearly fifty years old are not going to sound very good. I sold my early 1980’s Threshold Stasis 500 about 20 years ago and had Pass recondition it before the sale. It made a huge difference in the sound. 

thanks @waterford ​​​​@ghdprentice !

The Musical Fidelity A308 has a stout spec sheet! Well done, as that's what the Dynaudios seem to like best overall. 

I do notice that the A308 offers preamp output, so if you get the need to try other power amplification, there it is. Just kidding, but it's part of the pastime.

@parkergetdean ,

Making any progress?

I have not taken it to a repair shop yet. I opened it but was afraid to touch it. It turns on intermittently, I am waiting until it dies completely. It certainly soured my relationship with it, I don't blame the seller but it taught me a lesson about the risks of buying used.

I am going to text my repair guy to find out how much it could be (he will tell me he won't know until.... and we both know that even if it's a loose wire, he will say it was a 3 hour job and expensive part: $380) Nature of the beast.
