I picked up a Denafrips Ares after my USB-only Wavelength Brick was no longer enough for the TV and other devices that I wanted the best sound quality possible out of. I've been burning it in fully before trying any comparisons, but locally some guys have Yggys, a Holo Audio Spring Lvl 3, and some other DACs. Unlike the higher-end Denafrips DACs, the Ares does not have a non-oversampling mode (I mistakenly thought it did when I purchased it, though now I'm not bothered).
At some point in the next month I'll try to get some organized comparisons of the DAC with others. I'm definitely enjoying it in my home system.
