I have had stunning results w/DCS Elgar Plus and Esoteric.
Garebear - sorry to say, but I think you were misinformed. The Esoteric transports will work with most any DACs.
I currently am using my Esoteric modded UX-1P1 as a transport only for an APL-modded Denon 3910 with amazing results. The Denon has just been outfitted with AKM 32-bit DACs, new clock, wiring, and E182cc class A Tube output stage by Alex Peychev. The amazing part is that it sounds noticeably better than the UX-1 with my Esoteric Rubidium clock (which sounded great, btw) - more organic, better imaging, separation, soundstage depth, air around the instruments, etc. I wouldn't have believed it if I wasn't hearing it.
Good Luck to you.
