Howdy! As I posted in another thread, I am considering a Pioneer AV receiver as my "wildcard" in lieu of a 2 channel receiver or integrated. The model I am looking at is the VSX-LX503:\n\nThe ONLY reason being is that it matches my UDP-LX500. This will be used strictly in a 2 channel setup and they'll look real purty sitting next to each other!\n\nA couple questions if I may:\n\n1). Does anyone here on AH have any experience with the Pioneer "Direct Energy" (i.e., Class D) amplification and how does it sound to you for music reproduction?\n\n2). Does anyone here on AH have experience with Pioneer's MCACC and how does it compare with, say ARC, Dirac and, most importantly, YPAO? \n\n3). Is it possible to assign more than 2 channels for FL and FR duty, in essence creating an active bi-amplification scenario? It would be really sweet to have an RMS of 240WPC on tap!\n\nI have narrowed the choices of my next purchase down to this unit or the Yamaha R-N803. Any and all input, suggestions and\/or criticisms (as long as it has to do with these two chosen units or my moral character) are most welcome!\n\nCiao!
