Wish I could help; I'm using a Qsonix 205 paired with the tube DAC output of an Ayon CD-5s, then going to tubed VAC Phi Beta preamp to Hegel H-30 amp; and its much better than my previous PS Audio perfect wave DAC I...I use AES digital out, prefer it to Rca. Love my Qsonix, and touch screen, but matching to great DAC is a must; I'm certain that the PD products will also sound great. Sorry I can't totally answer your question....Enjoy
