I owned a Thorens 190 for a few months as an interim table. The tonearm limits your cartridge choices, but it was perfectly serviceable with the OEM Ortofon OMB-10, and could have easily been upgraded to the OM-40 with just a stylus change. Quiet, good speed control, and smooth tonearm setdown and pickup.
Is it as good as your Denon? Doubtful, but it's a case of "they just don't make them like that anymore". The Thorens is mostly plastic, as are most of the current automatic tables. If someone tried to duplicate your Denon today, it would probably cost $1500.
If you're willing to buy used, just get another DP-52F. There's one for sale right now for $125:
