Please check the tonearm mass. The importance of a proper tonearm mass and cartridge compliance match cannot be emphasised enough. If the tonearm is heavy (Above 12 ) only then go for the Denon 103. If its medium mass (8-10) go for the Denon Dl 110. If its on the lower mass side (<8), go for the Denon 103. All are at different price points, the least expensive is the dl110. Each has a different compliance to match the tonearm.
I would say go for the DL 110 for starters. It has the advantage of a high output and is a lovely cartridge.
