The only other software/setup tools you can use with that avr is the MultEQ-X software app ($200). You can't use Dirac or Anthem Room Correction, the avr just isn't setup for it. The newest Denons do have a Dirac license option, tho (3800, 4800 and A1H). What you can do, as Audyssey doesn't tell you what you've particularly started with nor ended up with, is a good measurement mic and software like REW (
Room EQWizard) so you can see not only starting conditions but also ending. Or just use it as a guideline and not use Audyssey, it doesn't work for everyone. Kinda depends how much time you want to spend on this. Your room is a basic limitation, so just setting up your room as well as you can without software is the best first step.
