Does anyone have any experience with Urei (Urie? Urey? Muffin?) amplifiers? I have a chance to purchase a 1kW amplifier for about $200. I know the seller personally and know he wouldn't sell me any crap, so I am assuming it's not top of the line. I have never heard of them before, and searches for Urei (which I HOPE is the correct spelling) end up telling me about the LA series compressors. Any help? The dollar to watt ratio is really tempting me here.
