The HDVA 600 amplifer used to be listed on the Sennheiser website as a recommended product for the HD800, but now only the HDVD 800 is recommended. I also see that retailers are listing the HDVA 600 discounted from the original MSRP of $1600. Does anyone know if the amplifier has been discontinued? Seems odd to me, but is it because it wasn't selling or is it because the HDVD 800 is much better? I like to hear anyone's opinion on this amplifier.
