I had the Holo May KTE for around a month. Great build quality and functionality but there was something incredibly irritating about that DAC for me. Same reaction I get when I listen to Chord Dacs... It was layered and textured, and more or less smooth, I wouldn't say warm by any stretch-more clinical. Issue for me was it was NOT musical at all to my ear, and quite honestly I think alot of the folks lauding it haven't really taken the time to listen, or audition truly musical DACs.
To each their own but that DAC was cold to me and not musical. Listen to an Audio Note DAC, or a Wavelength Audio DAC, or MSB or Total DAC, thats musical. I think this DAC is widely being mischaracterized as something it is not.
