This highly regarded step up transformer will turn your Denon 103 (all iterations) into a world class performer. It's a veritable magic box with nearly any cart that likes to see an impedance of around 100 ohms, or so has been my experience. The Dynavector Karat, for example, works well (I am selling one and will bundle it with the SUT for an extra $350).
No issues, just a few small marks from general wear and tear of two or three years. I pay for FedEx shipping and no fees to the buyer, the ask price is the total. Please feel free to ask any questions, and thank you sincerely for your consideration.
