I have been struggling for over three years with a buggy HK AVR 645 that crashes at least once a week and loses all its DSP and room correction settings. Every six months or so I check to see if Emotiva or Outlaw have come out with new processors, and no luck. I use an Emotiva XPA-5 amp and Wharfedale Opus 3 fronts, center, and tri-surround, Sunfire subwoofer. Music 70%, Movies/TV 30%. The room correction does seem to help dialogue be more discernable, as I have an odd shaped room.
I noticed that you can now get a used NAD M15 for under $1,000 and Rotel RSP-1098 for less. I'm tempted to do it. My 42" Panasonic Plasma is nearly a decade old and doesn't have HDMI input. It works fine, and I don't have the budget to replace it anytime soon. So HDMI isn't really a need. I'd assume Rotel and NAD would greatly improve the SQ of my two channel music listening. But I'm concerned about its lack of room correction.
I saw someone in a thread who got the M15 used for under $1,000 back in 2008 even. I wish I could find it cheaper, but I suppose value is steady if the quality is there.
I've researched Integra and some others, new and used, but I don't see anything comparable available for under $1,000.
I'm hoping experienced owners can chime in and reassure me that I can at least adjust levels of the center and surrounds manually. Something to tip me to one side or the other of pulling the trigger. Thanks!
