Still one of the very best SS amps in the world (and don't fall into the hype of every new amp released -- only the GSX MK2 and Dynahi -- bettered this amp and even then the Beta held its own). I have another Beta that is fully balanced hence the sale of this one. Fantastic bargain as nothing comes near it in this price range. Price is firm. Conus Preferred. Paypal gift or 3.5%.
