I wrote this about the Ultralinear:

Still cannot recommend LTA highly enough. Paired with appropriate speakers some of the best sound available in a novel design that emits little heat, with tubes that last forever, and offered by a company that is led by a super guy with a great team. These are David Berning amps built by a guy who understands manufacturing and customer service--nuff said.
