What tonearm is recommended for the denon 103r

Ortofon rmg is a very good choice. Also super when you want to try an Ortofon SPU in future ...

The Denon Dl-103's were designed for broadcast use for FM radio. You want a heavy arm like a Audiotechnica from that era.....

Old thread but still relevant, If you want an arm for the 103/103R then consider a Temaadaudio Merlin Titanium arm. In standard for the Eff mass is 22 grams, ideal for the cartridge & also ideal for Koetsu's. The arm was just reviewed by TNTaudio online mag & the reviewer stated it was the best arm he had ever heard

Cheers  

The new arm designed for Denon DL-103 and Ortofon SPU is "12 inch Thomas Schick (Made in Germany).

I don’t know how many times i have to post it, but to understand why low compliance cartridge must be on high mass arm anyone can read this Ortofon Article

Also the Technics EPA 100 original issue with ruby bearings with titanium nitride tonearm tube, works very well with the 103 Denons. The Techincs EPA 100 is rare now and very pricey if you can find one.

No, this statement is false, Technics tonearm does not work well with low compliance cartridges and it will be difficult to even balance heavy cartridge on heavy headshell using Technics EPA-100 conterweight. I’m the owned or EPA-100 and EPA-100 mkII tonearms. I wouldn’t use low compliance cartridges on them. But mid compliance is fine, high compliance also fine. For DL-103 or 103R this is not optimal tonearm. Fidelity-Research FR64s is much better match for DL103 series. 

However, there is one higher compliance Denon-103 made, if i remember correct it was DL-103D ?
