I notice that the DSP also provides support for dynamic signal compression (boosting low level signals and attenuating high level signals) which kinda sounds like the Auto volume adjust feature of Hijack. but a little more sophisticated. The DSP seems to have quite a sophisticated 'quasi peak level' detection thingy which might prevent having to manually tweak the current auto volume adjustment for different types of music.

There's also mention of three different modes for the Loudness control - the static mode sounds like the way the empeg works currently, but dynamic bass boost (adjusted according to the amount of bass in the input signal) sounds very cool. I guess this sort of thing detracts from the audiophile purity of the empeg, but most mid-market head units seem to encorporate something like this to add warmth to the sound. Several people have commented that the empeg can sound a bit 'thin' without loudness applied, however the current loudness control reduces the amount of boost applied at higher listening volumes. Perhaps dynamic bass boost would be a better solution?

Good work on this everbody!
