The 834 already has SUT's built in for the MC section, so you would be substituting the Bobs Cinemag SUT for the EAR's.
Whether the Cinemags would be better or not I'm not sure - would probably depend on the cartridge you're using.
FWIW, while I think Bob's Cinemag SUT is a great value, its hardly a giant killer. Compared to the Choir Audio SUT-H7 (using Hashimoto HM7 transformers) the Cinemag sounds less transparent and dynamic, not as finely detailed and has less bass tautness/apparent extension. The H7 is a pretty big step up (sorry for the pun) IMO.
BTW, both the Cinemags and the H7 share esentially the same step up ratios - so its an apples to apples comparison.
