Has anyone experience with a Luxman CX1 phono-amp?

After long years of playing cd's I like to explore the world of vinyl again. I've bought myself a used Denon DP 2500/Denon 103R and a Luxman CX1 phono. Where I live (The Netherlands) or on Audiogon I can't find any information about the CX1. I've tryed to connect the DP 2500 with the CX1 to the SE phono-entrance of the ARC Ref 3. Checked all the connections, put the frontselector of the CX1 to 'gain 20 or 30 db.' but absolute no sound. Tryed another TT (Sony 4750), no sound. I've connected the Sony (without CX1) to the ARC phono-entrance. You hear the TT play. The powerindicator of the CX1 lights up, the fuses seems to be okay. Ref 3 automatically changes from XLR to SE. Can there be a conflict SE/XLR on the Ref3 or with the CX1 (MM/MC) ?
