Hello, I am looking for the right receiver. Presently using (please try not to laugh) a Pioneer Pro Logic Dolby Surround system. I was young and didn't know what I know now. I have been doing some research and am not in a hurry but would like the right fit. Budget plays a big role so I am looking at a Sony STRDE575 and Technics SADX750. According to audioreview.com the Technics scores better. Just to make things worse there is the Kenwood VR-506 & 507. I am looking for some input on this.
