I tried the a/b without DEQX/with DEQX online demo at the deqx site with a pair of decent headphones. Glad to say most of what I hear at home off my OHMs with CLS (Coherent Line Source) Walsh style drivers sound much more like the with DEQX samples, as I would expect. Also I can relate to how things degrade from there in some other cases I am familiar with to various degrees, though the "without" samples in the demo sounded pretty extreme.
No doubt the "with" DEQX samples are much easier to sort through than the "without" samples.
