Cartridge recommendations

What is the difference in sound between the Denon 103 and the Denon 103R??  Is it the type of stylus shape?? or better sound quality. Th Denon's MC's  also have notoriously low output... like .030.

Even the DL-110 MM  is only 2.0 mV which is low compared to Ortofon cartridges and some other MM's  What about the Nagota cartridges from Japan, like the MP-150 which gets very good reviews   

There's a Shelter Mk iii on ebay right now, $795. One year old.

Maybe a Denon DL-301 would be a closer sound to the Shelter than the 103.

It's pretty funny when people suggest something they have probably never owned based on review online @sunnyjim 

DL-103 has conical tip, people love it or hate it, to my ears conical tip is the worst ever and it will be the worst choice for people who love extended and detailed sounds. Reviewers will tell you the conical Ortofon SPU is very musical cartridge, but in reality (at least for me, in tube high efficiency system) it is dull and uninvolving with lack of details on both ends. This is total oldschool. It is in the same caregory as cheaper DL-103. So many cartridges does it much better and so many vintage MM carts sounds incredibly good for the same price as conical DL-103 or elliptical 103R. People invest in mods of 103, but for the cost of this mods they could buy much better cartridges without any mods required. I just don't understand it. Denon S1 or DL1000 were the best Denon cartridges this company ever made, not the 103 or 301 series.
