Recently, I was in between cartridges for various reasons and in order to make do resurrected my old Denon DL 103. I took a great deal of care to set it up correctly.
I have to say I am really stunned at just how good this cartridge is - no modifications, just the stock standard DL 103. In particular, I am amazed at the tonal richness and mid range beautify of this cartridge. It is just incredibly enjoyable to listen to.
I am waiting for a Zu modified Denon to arrive and can't believe that that will be any better.
Given how good it is, I think I would be reluctant to muck around with mods that might change its tonal beauty like changing cantilever, stylus etc.
