If you're thinking about the Bob's devices SUT get a Parks audio one instead. It is the identical unit for 1/3 the price. I have no experience with the ear but I wouldn't think that the Bob's devices would beat the transformers in the ear. And there is a lot of sense in people saying save your money and take a bigger step. One phono to look at would be the Herron.
Add Bob Devices CineMag SUT to EAR834P Deluxe
I have a chome EAR 834P Deluxe, which already includes an MC option. However, this CineMag has received great reviews. Using the EAR 834P in MM mode, in conjunction with a CineMag might be a worthwhile upgrade? What do folks think? I have a Shelter 501 MC cartridge.
