Beat me to it!
5 Band parametric EQ with individual L/R adjustment, 1/3 octave (from memory) selectable frequency centres, Q values selectable from 0.5 to 12.0 (in steps of 0.5), gain levels adjustable from -12dB to +12dB (also in 0.5dB steps) and the complete freedom to overlap bands to your hearts content if you so desire. It's this type of flexibility which IMO separates the HX-D2 from all other all-in-one head unit on the market. The only real restriction imposed by the EQ is that you can only use three of those 5 bands on lower frequencies - the last two bands can only be used on frequencies fom 630hz and upwards. A small limitation, but something I can live with because I still feel the EQ us the most useful on the market in a unit of it's type.
The time alignment (0cm - 520cm in 0.7cm steps) is also one of the - if not
the - most comprehensive of any such unit on the market. Then you have the 0.5dB stepped volume adjustment, which I don't think any other head unit has (though I could be wrong).
The crossover is really the only part of the unit I find restrictive, with only 6dB/12dB/18dB slopes available. I personally like to use the steepest slope available 90% of the time, and the lack of a 24dB slope option is really a step behind considering every other brand (Alpine, Eclipse, Pioneer) offers this on their high end units. It's something I can definately live with, but it could definately use an upgrade.
All of this is why I've fallen so much in love with the HX-D2, and no matter what other units I try (Alpine CDA-9813, Eclipse CD8455, Clarion DXZ756USB) I always end up going back in the end. 0.5 increment adjustments on everything, 24 possible Q levels and the freedom to do whatever you want with EQ bands are things you tend to take it for granted, but then as soon as you switch to another head unit you realise how much difference all of those little things made. It's the combination of all of these little things that makes the HX such an impressive package to me.
I have to agree though, abiltity to play WAV files from USB would be nice. That said though when you consider the size of WAV files (~40MB average) the ~800 song storage still wouldn't be enough and it would be sucky to navitage with a test based interface like the Clarion's. I wouldn't say no to the option though
