What is the appeal of the Denon 103 cartridges?


I know they have been around years. However, I see many music -gear reviewers with super expensive turntables running the Denon 103/103r. I'm thinking of trying one myself, possibly one of the ZU adaptations.

Pretty simple. They can sound absolutely fantastic when set up right and shouldn't break the bank. Been through many carts in my day but discovered the dl103r a good while back finally and it still thrills and captivates years later.  

Just to add, it's also bull that it needs to be used in some super heavy tonearm. It will sound just fine in a medium mass arm. Have one installed on my thorens td 1500 with 14 gram arm, sounds good to my ears.
