Yes, FLAC could always be handled with an external device. I simply like the idea of consolidating where I can, and it's not an unheard of feature in receivers anymore.

I'd rather not have an extra device handling subwoofer EQ, though. That was the thing that annoyed me about the SVS AS-EQ1. It would be so much handier to have it handled in the receiver or processor as part of the normal calibration. But yeah, independent calibration of two subs seems to be a reasonable request now, so if nothing else, I can calibrate my subs as two pairs. I'm simply surprised no one is offering four-sub calibration yet. You'd think someone would have a high-end offering that would do it, even if it's out of my price range. Or maybe it's out there and I just don't know about it.
