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

I agree with the Jelco 750's synergism with the Denon DL 103 and even the 301II. I have 2 turntables [18 cartridges] on which  many cartridges work quite well, not to mention the ease of changing cart's with the Jelco's detachable headshell Jelco tonearms, are my favorites with my 2 Denons, plus they come with 2 counterweights to accomodate less compiant and more compliant phono cartridges and are comparatively inexpensive.

I love the last three posts and earlier on suggested a Technics 1200 with mods to the OP. The Jelco arm being a perfect example of such upgrade. The audiomods arm is another interesting design that I haven't had a chance to hear but looks worthy of further investigation. 

@sunnyjim Yes, I know people with the Spin Clean who like it. It's not going to do the job like an Ultrasonic, or similar, but it looks like the lowest cost non-DIY way to take your cleaning to the next level. 
Many are upgrading their rcm these days, and used VPI 16.5s are plentiful(I sold mine a few months ago too). They are a notch above the Spin Clean and built to last, but at a high cost. Cheers,

@ Chekster: About 103 vs 103R: the difference is stylus tip

NO! The Stylus and cantilever are the same. The difference is just coil material and output impedance.

Sorry, my mistake.
It's Denon 103D that comes with more refined elliptical stylus tip. 
Personally i would avoid any cartridge with conical tip, i was so disappointed with new conical Ortofon SPU Classic GM mk2 that i bought based on review. Later i realized it's definitely not my kind of sound. Same with MM alternative of DL103, which is DL-107, made for NHK Japan as their official studio broadcast cartridge. Good cartridge (maybe even better than 103), but their super-duper polished conical tip does not sound as good as shibata imo.
