I am the first owner of this Reference 150 power amplifier - purchased from The Listening Room, an Audio Research dealer in Maryland. I have loved every minute of owning it, and I am selling it only because of a low price now on a new Reference 150SE. It has 7,298 original hours on the clock, and is in perfect, like-new condition with no blemishes or marks. It is in a child free and pet free home, with hardwood floors and minimal dust in the room. I have both a set of KT120 and KT150 tubes, almost new with no more than 200-300 hours on them. The price includes shipping via UPS in the continental United States. No lower offers will be considered.
