After reading long threads here and on head-fi it seems most people are happy with DEQ, although I noticed just few that have actually audiophile systems - to be able to evaluate and compare fidelity levels.
For this kind of money it worth a try anyways.But I would like to find more information how good the digital processing implemented in DEQ. Some say "it's OK", but it's not very informative.

I don't know much about how the DSP algorthms are implemented in the DEQ. I would imagine that a group like TaCT uses far more current DSP routines in their new units.I have tried a couple of different features of the unit. My results so far are that using the parametric equalizer for limiting peaks can lead to excellent and transparent sound. I have played around with the stereo width feature but not too much.
I've tried running the auto eq feature and acheived terrible results, although I haven't spent much time with it and can't say for sure if I was doing it correctly. The auto eq system uses the standard graphic eq instead of the parametric eq. The parametric eq gives you much more control than the graphical eq because you have a fair number of preset center points and can control the width of the filter from at least 1/10 an octave to 2 octaves, as well as the level of gain or cut in half db steps up to 15 db. I wish that I could exactly control the center point frequency of the parametric eq presets because that would take the unit to another level usefulness in cutting peaks outside of the bass range. The graphic eq is locked in at 1/3 octave width for each of the 31 preset bands and hence is much less useful for correcting real room problems.
"I wish that I could exactly control the center point frequency of the parametric eq presets because that would take the unit to another level usefulness in cutting peaks outside of the bass range."You may already know this, but just to make sure...
When adjusting the filter center frequency, pressing the large data knob alternates between 1/6 oct and 1/60 oct steps in the center freq.

Actually, I did not know this. Thanks very much!
