I think Chord's WTA filtering sounds different in the same sense that zapping through an assortment of fast and slow linear or minimum phase filters will sound different - not a huge difference but some will find a preference. If there was one such filter that was 'coming home' to my ears, where nothing sounds bright or too fast and slow and the music just gets through - that's how I experience Chord vs the rest, having heard Mojo, Hugo 1, Qutest, Dave.
My most recent purchased were RME ADI-2 DAC and Sabaj D5 so that's one top AKM DAC and one top Sabre DAC, both sounding more detailed but I revert to Hugo 1 after a while every time. It's as if they cut the music from slightly different cloths and I personally just feel at home with how the Chord sounds.
