I'm using the xover with stereo subs: 100 Hz LR @ 24dB/o with a small delay on the mains.
It sounds fabulous. I've spent less than an hour on setup and tuning, hope to invest more time over xmas.

Did you compare the two options - SHD as control for the crossover (like you did it) versus subwoofer hooked on hi level input direct to the speaker output on the amp ?

Actually every sobwoofer manufacture says the high level input is the best way to connect a sub because only doing so you get the right timing and the specifics of the particular dac/amp.

You sure? I just looked up three subwoofer manufacturers (SVS, Neumann and Genelec) and didn't see speaker-level inputs on their subs.

fair enough ... ... those who have one
anyway, the question is if there is a difference

In general the speaker level connection seems to me to fall squarely in the "really bad idea" department. I know of an amp manufacturer that damaged one of his amps, not realizing that the negative input on the sub's speaker level input was shorted to ground. (The amp was a class D with DC on both outputs). Plus the other stuff with not being able to control the crossover/delay.

JMHO and of course, YMMV

Timing is one of the many features that these amazing miniDSP things do
Once you got 4 dsp-enabled channels, you can forget most of the mortal people's problems

if there is 1 thing you cannot influence this way it is timing. one of the great things of using a DSP for the sub is to be able to use the right delay. and the ability to correct the sub and mains independently, and to set a proper cross over to the exact slope and frequency, and not having to guess with a small knob.. and then some more...
