The reason WHY A&H sounds warmer than Pioneer

Just grab the mixers in question, run the same output to all of them. Run the mixers into a daw and compare them using parametric visualizers, spectrum visualizers, and oscilloscopes. Hell you could even route the source audio into the DAW at the same time to use as a baseline. You could then see which mixer reprodced the source audio the most accurately. ;-)

Yep. I've also done that with some of the DJ software out there. I need to do it again on them one of these days, as there have been quite a few updates in the last few years since I did that.

Traktor and it's famous "internal EQ affects the sound even when in external mixing mode" problem? Yes please

I remember on Traktor 2 Pro when I was testing most of the DJ software out there that the key lock algorithm wasn't actually turning off completely at the time. Once you triggered it, it mangled the impulse response to hell and then deactivating it wouldn't actually resolve that until the program was rebooted. They fixed that and some other issue I informed them about concerning pitch bending. I was quite impressed with the 16bit VDJ 7's processing. Very clean and precise. There's something to be said with not oversampling, doing lots of interpolation, and then dithering the hell out of it at the end. I know they've moved to 32bit now and their key correction seems wildly improved in 7.4 and 8. Torq 2 was appalling. I don't know what the hell was going on with that DSP coding of theirs. The basic specs it produces weren't too bad, but it couldn't deal with a lot of test waveforms. I think its impulse response was practically non-existent and like inverted or something. Sounds real dark, crunchy, and processed, too. Has an unmistakable signature it gives everything. The old pre-Pro (not sure if that's what it was called) 2 channel version of Traktor had very pleasant sound and good tests.

because if they got it they would feel really guilty about spending so much money on cables.

You can never spend too much money on cables. :-p

Can I say how much I'm enjoying the resurrection of this post? It's quite possibly the most interesting necropost I've ever read. Thank you to all involved.

I recently hooked up my DJM-900NXS2 to ableton and ran some pink noise through it and observed the isolator work in a RTA graph and made a virtual NXS2 isolator EQ rack. From my expirience the NXS2 is quite a bit warmer than the old NXS. I have heard the analog A&H mixers are still wamer but I have never had the opurtunity to try one out.

In audio testing it really is. This has been proven experimentally time and time again. The entire audiophile market of pointless products also proves this.
