To be clear, I would sum up my complaints in two issues:
- Immersiveness
- Bass response
Listening to well mixed DVDs I don’t feel surrounded by the environment. I feel subjected to it. The bass also doesn’t feel well integrated with the rest of the system. I can hear all 5 main speakers, but I don’t feel surrounded. The front channels never fully merge into 1 audio presentation, and the rear speakers also feel separated from the fronts.
In my experience, this is something you can do with 5 speakers alone, you don’t need Atmos to get to this level of performance. Just good speakers, a good room and careful EQ. An approach at least a little validated by Floyd Toole's writing on "room correction."
My personal approach to EQ is very different from Anthem. Anthem picks an ideal curve and tries to get all speakers to match it. I used my mains as the reference and made the 3 remaining speakers match them. I also set the bass to go down to 16 Hz and descend about 1.25 dB/octave.
Another way in which my approach differs from Anthem is that I only use 1 measurement point. Trying to set all 5 speakers to an ideal curve, across multiple measurement points may be correct on average and exactly wrong where I listen.
Lastly, when I do EQ I do so sparingly, attempting to use the least amount of filters and least amount of correction as possible, giving myself more freedom in the bass to fix room modes than in the mid to treble.
For all these reasons I want to try a Marantz HD processor next. The advanced Audyssey levels let you craft your DSP curves completely by hand.
