Sad to say I need a new amp…

I would buy anything but VanAlstine.  I had a worse situation with them than scuba535 with Upscale.  Granted this was over 20 years ago, but had a very much loved early ss amp of theirs.  It went on the fritz, wouldn't power up.  Called and was told that they don't work on their older products.  I asked if they could send schematics that I could take to a repair shop.  The answer was, no, those are proprietary.  So, what I ended up with, that was once a wonderful sounding amp, was now a good door stop.  This eventually ended up in the trash.  Yes, I did get some grief from friends with McIntosh and Audio Research that had older gear than mine that was getting serviced when needed.  I hold a grudge that lasts forever.  Great sounding unit, but just enjoy it while it works. 

Underwood Audio is releasing new equipment including amps.  In my opinion cannot beat the price performance.  I would give them a call.

Ibmjunkman: Mesa got in and out of the home stereo space years ago and pretty quickly. They also had a amplifier known as the Baron which was I believe more powerful.

take a look at Decware the plus is lifetime warranty don't see much of resale side from what I have found is they are pretty good all hand built

If long term reliability is a priority, I would stay clear of NAD. Excellent engineering & sound quality for the $ but build quality lacking. Had a preamp & their best surround sound receiver fail just after the warranties expired. Receiver was supposedly upgradable w/ plug in modules which turned out not to be the case as well. Anthem & Bryston products are well made, sound good & should last a long time. Maybe check  them out.
