Jay's Audio CDT-2 MkIII, it's a great transport and definitely ups the SQ game. I own an Audiolab CDT-6000 (which is a very good transport), but the Jay's blew it away. It's what I'd buy as of today, but I'd definitely test the Teac 701 as well.
If I2S is important (which it is for me as my Denafrips Pontus II sounds best with this input), then the Jay's Audio transport is the better option.....the Teac does not have an I2S output.
