DAC for my Esoteric X-O3 SE??

A very highly regarded player to resort to experimenting with dacs in my opinion. More highly regarded than the x05. But to each his own.

I was just wondering, since my Esoteric is four years old if there was a quantum leap in store if I purchased a state of the art DAC

For what it's worth, I have an Esoteric X-03 SE into a Bricasti M1 with a HiDiamond Ref cable, RCA to BNC. I like it.

I own an Esoteric UX-1 and I found out that adding a Yamamoto YDA-01 or an Exemplar-Xindak DAC the sound improvement was -and still is- huge.

Both Srajan Ebaen and Jean Hiraga at one time owned the Esoteric UX-1 and interesting preferred the Yamamoto DAC than the Esoteric`s internal DAC. Same as you Daniel.
I use The Yamamoto DAC and find it superb and utterly natural.
