I've bought this HPA D500 (An ex-demo model from a Germany store) on 21/11/2015 to power two ceiling speakers, but due to several constraints, never used it, and actually the box was never opened. I think HPA is the base company for models from companies as Cervin Vega, American Audio, Samson, etc. Specifications: More details here: HPA Co.,Ltd. Delivery cost is included on price.
