I'm only interested in bass correction/integration (<100 Hz) for my entire setup.
Ever since getting my Expression 13A's, I've struggled to "dial-in" my two ML BF210 subs (to minimize the wide 50-60 Hz null at my main listening position). The 13A's, after running ARC Genesis, yield extraordinary tight and musical bass down to ~24 Hz, but (as expected, due to room geometry) can't eliminate the null. Running ARC Genesis (separately) on my pair of BF 210's, pretty much fills in the null (as expected), and brings the bass response down to ~21 Hz. Unfortunately, when combining the 13A's and subs together (even with the appropriate downloadable filters for the subs), the bass gets muddy and bloated, due to misaligned phase/timing. The Anthem STR Preamp also has the ability to apply ARC Genesis simultaneously for the entire setup. However, I needed to replace my ancient Denon receiver anyways, so I'm hoping the MRX 740 will "kill two birds with..." I know the MRX 740 doesn't yet offer sub distance calculation, nor automated phase alignment, but that's supposedly on the horizon at some point. Until then, at least I'll be able to manually enter (and experiment with) the values for sub distance.
