Upgrading HT and 2channel stereo

Sorry to disagree with Mijostyn, but there are way better ways of doing this and using the MRX Receiver with a higher quality power amplifier.

The idea of the receiver to power the center and rears is a good one, the area where we would differ, is to use a high quality intergrated amplifier with a home theater bypass function, along with a high quality dac/streamer. 

The reason is simple any surround sound processor does a poor job as a two channel preamplifier/dac. The reason is simple economics, a surround receiver has 5-11 channels of preaplification, 5-11 channels of dacs, Dolby and DTS decoders along with a video switcher, way too much circuity that generates noise is being injected into the music signal.

For this reason a pure two channel integrated will often sound far more dimensional with better resolution than the surround sound receiver even with a good power amplfier. The Parasound A21+ is a good power amplifier and even with the excellent Anthem Receivers, for music a Coda, Hegel, Luxman, Naim, Unison Reseach integrated will offer a far more realistic recreation of  a music event than the other setup.

ironmike you could do a great system with an Anthem MRX 510 for $1,400.00 and a good high power integrated for $3-5k and you would have a great package.

We have the new Unison Research Unico Due a 120 watt hybrid integrated with a tube front end and a fantastic built in dac for $3,800.00

Your package therefore would be that $5,200.00 for a great amp with a great dac, and a fantastic surround sound receiver. 

Another great integrated is the Musical Fidleity M6si a 225 dual mono power house for $3,000.00
