I am currently using a NAD T773 avr mfd. around 2004 with an Oppo BDP-83 and Klipsch RF-63 system. It is powerful and very musical. Never an issue or hiccup at all with this piece. Used prices from $350.00 to $600.00.
Any of the B&K models(AVR305,307,505,507) wi11 be very musical and powerful and will do just about anything non-HDMI.

This one is on the high side but a great receiver indeed.

This Yamaha was the flagship receiver in 2003.
