Based on things I've read over the years, and since I already have a DL-103, I had sorta decided my next cart would be a Zu DL-103r. Now I'm back to being on the fence. As others have pointed out, the DL-103r is interesting in that some people vociferously insist that it's not just a little, but *a lot better* than the DL-103. I've read some pretty impassioned comments over the years from owners of the DL-103r who've gone into great detail about the various points of superiority the R version supposedly has over the plain 103. Much of it that I have read boils down to the belief that the R has more in common with "true hi-fi" carts than the 103. On the other hand, lots of other folks, the guys at Zu among them, seem to think the 103r's main distinction is a bit of a treble push. I think slightly divergent schools of thought around what constitutes "hi-fi" has something to do with these two interpretations of the 103r's presentation. I love my DL-103 - I've been using a Conrad Johnson PV-5 phonostage lately. It has ludicrous amounts of gain by today's standards, so today I rewired my SUT from 1:20 to 1:10. The lower gain and higher loading are really bringing out the best in the 103.... Really nicely fleshed out, open, extended and also balanced. I'm not sure I'd want more up top... particularly on Altecs.
