Any of the Denon SUT's will work fine. I have one in use with a 103R. Along with a Bellari and a Quicksilver plus three others (Sony T10 and two custom-built with mic transformers). Loading is a matter of personal preference for mc's - experiment and listen!
Need recommendations for a Step Up Transformer for Denon 103
I have a Denon 103 that needs a SUT. I'm told that the Denon performs best when loaded with 470ohms. I'm new to the world of SUTs and would appreciate recommendations on a SUT that can achieve this specific loading or one close to it. My budgiet is ~$500 but preferably less. I've heard good things about the Ortofon ST-7, Parks Audio Budgie SUT, and the Rothwell MCL...
