Thanks guys. Very interesting. As to room interface @JimK, I agree. I have a dedicated room designed by an acoustician with the correct treatments. So fundamentals taken care of. I just am sensing the lack of options my processor gives. Right now its meeting my needs, but I would like to stay aware of other options. Critical for those of us who have bought into the whole system. Its a substantial investment, it's worth paying attention.

Best regards,
Jerry
