I currently have a Harman Kardon DPR 1005 and am considering a new receiver with HDMI. Is the Onkyo TX-SR608 a better receiver? I know the HK doesn't have HDMI and the Onkyo does. Sometimes the HK acts funny (Not HaHa funny) as in, when turned on the volume level is different than when shut off. This can be obnoxious. It has had other quirks as well. What is your take on the Onkyo? What about buying any of their refurbished units? Will HDMI really improve sound quality enough to warrant a new receiver? Should I be looking for maybe something bigger like the 707, 708, 807, or the 808?
By the way, I have a $400 gift card from Best Buy burning a hole in my pocket.
