The Denafrips Terminator,and term+ , 12th anniversary and HoloSprings May KTE dacs
are substantially better ,you mentioned Chord these dacs are sonically more natural and musical then the Chord Dave , the dacs you have are a older generation . I am in a multi state audio club and have heard the vast majority of equipment out there ,sometimes very expensive .
just look at the Many reviews on these dacs, the Denafrips 12 anniversary I only heard briefly the + is better still , these did into the recordings without being over analytical like the Dave dac can be ,and is even more $$ . This I can guarantee
you buy any of these above mentioned dacs ,sell your 2 and you are will be much more musically satisfied. Having been a Audiophile for 4 decades and owned a Audio store .digital has finally arrived over the last 2-3 years.
