DIN or RCA phono plug--which is 'better'?

One of my cable suppliers says DIN is superior to RCA in tonearm cable applications.

However, he prefers XLR to both of them.

Jonathan, if the TA connectors we're used to seeing on SME's for instance, aren't real DINs, then what does DIN stand for in that instance, or is it a misuse of the term?
Thanks

There are many different DIN connectors.

The RCA connector is inherently flawed in that there is no standard i.e. there is no guarantee that a given male will mate snugly with a given female, always a bad thing. There are other connectors that are much better, such as DIN and XLR, but we seem to be stuck with the RCA for single ended equipment. Some manufacturers such as Naim tried to get away from them but it never really caught on. Now Naim equipment comes with DIN and RCA connections.

Thanks, guys. I am asking because KAB has finished DIN
& RCA terminal prototypes for the Technics 1200's tonearm. Can choose either one for my deck. Kevin is offering Cardas Litz for the tonearm rewire, seems the Creature is getting to where it should be...at last!

Next is choosing the phono cable. What a mess!!!!

Nsgarch:

I have not been able to find mention of any such connector in either the DIN or JIS standards. Ditto according to my manufacturing sources in Japan (who just call it "tonearm connector").

I believe that it is a misuse of the term. Probably one of those cases where someone calls an item by the wrong name, no qualified individual is available to contest the misinformation, and it spreads into general use. Not so uncommon on the internet.
