Having read the review of Dirac sound correction and the review of the Arcam AVR21 that is looking like a potential purchase. Dirac looks to be the way to go. It should provide a big improvement over YPAO.
With just 7 channels of amplification (same as the Anthem 740) that suits me more than 11+ with Denon. Paying for something I’d never use.
I’m not discounting the Anthem 740. Just need to read some more reviews to see if the same strengths are made with different reviewers. Ditto with disadvantages.
Agreed, research is fun.
