Hello, excuse my English, but I am French and I go through a translation platform I have a PS AUDIO DAC I am currently using a MATRIX AUDIO X SPEDIF 2 interface I am very happy with the sound, but in the bass sound, I find that it is not very well defined. I bought very good quality USB and HDMI cables. Do you have the same problem as me? I would like to buy another interface the AUDIO GD DI 20HE, but I don’t know if it is compatible with my perfectwave PS AUDIO DAC. Is the sound quality of this interface better than the MATRIX? thank you very much eric ---
