Regarding the 978, I've already made known my request for Audyssey MultEQ XT32 (with bundled Sub EQ HT... all current implementations of XT32 include this) on the "Christmas" thread.

I would also like to see finer "granularity" in the available crossover frequencies for bass redirected from the sats to the sub, i.e. every 10 Hz from 40 Hz to 120 Hz (rather than every 20 Hz). So, if I get my way, the available crossover frequencies might be 40, 50, 60, 70, 80, 90, 100, 110, 120, 150 and 200 Hz.

Perhaps the main issue I have with the Trinnov implementation in the SN R-972 is that if one tries to tweak crossover frequencies after Trinnov calibration, the entire room EQ and spatial optimization suite is disabled. Audyssey at least lets you do minor tweaks without penalty.
