Thanks for all the thoughts and advice. I do plan on pairing the setup with a external power amp, if I decide to cut up my movie system (with the Marantz receiver as a preamp). Looking at the Emotiva 2-channels for that. I am still unsure of which amps/receivers to use, since some of my vintage Marantz and Sansui pieces sound very nice, but could sound much better with better speakers paired with them.
