I have bought a pair and have been enjoying them, my only complaint would be the lack of bass and some bass distortion when EQ’d. Other than that they are as smooth as eggs, very natural sounding but suffer more in some bass heavy and attack heavy songs.
Would love to see some measurements on it, or EQ suggestions. The best amp/dac pairing I found was the Shanling H5, really added a lot of punch and liveliness to it, while giving them a tube-like warmth. I tried it with 4 different dac amp combos, none of them were anything like this. The H5 has an output impedance of 4-6 ohms, so maybe that is affecting the frequency curve in a pleasant way
