- of course time is not accurate,
After so much talk of timing accuracy in your DACs, I'm surprised to hear you say that, Rob ...tssk tssk

Wouldn't that make the DAC more complex? Those tools belong in the source, I'd think. Or better yet, in the new digital amps that Chord are working on.@Rob Watts
I have discovered and fully embraced parametric equalization within JRiver and using simple spectrum analysis tools - have an absolutely flat response on my speakers and more low end. Its quite spectacular ...provided all my content goes through JRiver. Its a shame that my SPDIF feeds don't benefit.
Rob, any chance of including a parametric equalizer at the tail end of your DAVE(-2) digital section? Even supporting a low/high shelf or two would be very helpful to then allow all inputs to the DAC properly equalized. While you are at it, just incorporate a microphone input (ala Davina) and build in an automatic room/speaker optimization tool: Perfect analog reconstruction + perfect playback tuning.

My Blu-Ray/cable source is S/PDIF or Toslink. I too require DSP to tune out some subtle room bass peaks. Unfortunately, the best I can do is to get miniDSP nanoDigi and program it for the DSP but it inevitably converts 44/48kHz to 96kHz first which obviously means I'm losing timing accuracy and the wonders of all the extra taps in DAVE. Also to achieve maximum galvanic isolation between the Blu-Ray player and DAVE, I use toslink to feed the minidsp and use Uptone LPS-1 to power the minidsp. Definitely a suboptimal solution until Mr Watts decide to tackle EQ.Its a shame that my SPDIF feeds don't benefit.
Actually, EQ is something I plan to investigate post digital power amps - if I can get some subjective benefit from it. I have designed bi-quad DSP's before.
I think it would be more interesting to have active speakers where each drive unit has a dedicated power pulse array driving it. Each, of course, would have band-limiting filtering for the driver it's powering. Then, "room correction" is a secondary function of these digital amplifiers and there's no stupid passive crossover sucking up ridiculous amounts of power.
Since you're expecting to be able to get 10s of watts of power from a power pulse array in the first iteration and since there's no passive crossover, the resulting speaker should be quite something.
Now, to find a speaker that's amenable? ATC?
