When the PSA2's were new they were great, as they age they develop problems. High speed fans running for no reason, inconsistant turn on sequences, and when they blow up you can nolonger get ourput transistors. I have owned two until they both blew up in the same week. I replaced them with a pair of Crown K1's about five years ago.

Ps. I also have four DC300 Series 11's and love all of them.
