I have Marantz PM6004, CD6004 and Panasonic DMP-500 bluray with Monitor Audio Bronze 2 speakers. Looking for new receiver to connect with stereo amp (to keep stereo set up the same). Torn between the Marantz NR1504 and Yamaha RX-V673. Not many reviews of the Marantz/difficult to audition. Has anyone compared the two? (Yamaha is available for around £350 now). I do like the look/build quality of the Marantz (both appear to have L R Audio pre outs to connect to stereo amp).
