@audioman,
I think that based what you are describing, the issue has less to do with needing better DSP modes such as "3D" and more to do with one of the following: the class and output of your amplifiers, how you might have the processor set up, and/or the Audyssey room correction software that you are using. To start with, check to make sure that you have your channel levels, speaker types / distances and subwoofer crossover correctly set to ensure that your system is properly configured, and if that doesn't correct the issue then it's likely down to either your amplifiers or the Audyssey calibration software - have you tried turning it off to compare the before and after effects?
If the issue turns out to be with Audyssey, you'll need to either leave it off and just accept the way your speakers and room sound on their own or look at purchasing a new processor or AVR with a better room correction platform. While not a bad product by any means, the problem with Audyssey is that is uses a very flat frequency response curve, which despite popular belief is not the ideal model to utilize for the majority of room layouts and equipment configurations; it tends to be too soft on bass and too strong on treble, creating a very hollow and tinny sound that can be quite harsh at higher SPL levels. The other issue with Audyssey is that is only corrects frequency response and does nothing with time (impulse response) or phase, which are just as important, if not more so.
If you are comfortable increasing your budget beyond what you would have likely paid for the Marantz, there are two options on the market that offer superior room correction software: Anthem's ARC, which is excellent, and Dirac Live, which is easily the most advanced platform on the market right now and is currently offered by a handful of companies such as Arcam (full version on all current AVR's and processor) Emotiva (LE version on processor, which is a scaled-back version), DataSat, and Theta Digital (full version on processors, but way beyond the price range you are likely shopping in). Since preamp processors tend to be more expensive than AVR's, especially those mentioned above (with the exception of Emotiva), I'd recommend that you look at an AVR instead, which you can use as either a preamp processor with your existing amplifier setup or on it's own as a turn-key solution.
Let me know if you have any other questions of if there is anything else I can do to help and I'll be glad to assist in any way I can.
Take care,
David
