I agree with Raul. You may get by with a step-up, but this is unlikely to reveal the cartridge's potential. IME the DL-S1 sounds best loaded under 100R. This reduces gain further, compounding problems for all but a high-gain phono stage. I load it at 80R. A few owners have reported optimal loading at 30-40R.
It's an interesting cartridge-- one of the few MCs with non-permeable coil formers. This design choice may account for its high performance at the cost of reduced output.
