What turntable and TONEARM brands sound best with the Denon DL103 and DL 103R? MC's

The first question, as usual, is what is your budget? These low compliance carts require a high mass tonearm for best results. An idler-drive table, 12" heavy arm and DL-103 is the very definition of synergy.

Thomas Schick "12 tonearm made for Denon 103 if you’re looking for new tonearms for reasonable price.

About 103 vs 103R: the difference is stylus tip and coil wire, the "R" is superior compared to 103, but if you want even better look for higher compliance vintage 103D which does not require heavy tonearm to perform at its best.

Cartridge does not require a specific turntable, good cartridge works on any good turntable. Dedon made fantastic direct drive turntables, most of the Japanese broadcast studios equipped with direct drive like Technics Sp10mk2 etc. Denon 103 was made for broadcast use along with DL-107 (MM alternative of DL-103).  

p.s. you can easily google all info about denon variations and tonearm matching, this is not an exotic item with no info about it, tons of information online. 

@sunnyjim Are you giving up on the U-Turn already? We didn't get a post of your evaluation of it as you promised. Thought your plan was to use the Ortofon 2M then replace it with a Denon 110? Did you try those and decide to back up the plan a step or two?
Is your budget still $1100?
Cheers,
Spencer

Yes- are you taking a U-turn sunnyjim (-:
