Threshold s/500 vs Cambridge Azur 851 CD

Below is a Legacy Amp, made by CODA, excellent build quality. Might be tough to find, but look for CODA Amps: Model 10, 11, 12, 20, 30 & 100. They have been in business since 1990 and I carried the line when I was in the business. Also checkout Monarchy Audio.

If you want Threshold quality and balanced inputs, checkout CODA amps. Both are several steps above the Cambridge.
