Iv got a Visonik V4000XD. I wanted 100 shipped. 28 FETs on the power supply are blown. I got a qoute from db-r electronics for $175. The amp looks great pysicaly. Rated at 3500W at 2 ohm, so if you turn your gain down, you would be fine. Good way to have a $400 amp for $275. The amp also shares boards with the Ma HK4000d. PM me if your interested.
