how long of a break in for 17d3

I don't know your TT and phono pre, but at 10 hours my 17D3 (with a Nottingham Spacedeck and Dynavector P-75 II) was a bit on the aggressive side. It got fractionally better over the next 20 or so and then started to relax noticeably. By 50 hours, it was, I guess you could say, singing. It's a very fast, but musical cartridge, worth the wait and very worth the asking price. My two cents. Good listening!

I have a new 17D3 on a Rega P5 with a Dynavector P-75 II. After 60 hours this cartridge sounds somewhat better than initially, but it is not singing for me. I don't know what to make of it.

I was doing a search and found this thread. I am considering purchasing a CAT Ultimate.

I assume it is able to work well with the Dynavector 17D3 and not have too much noise considering the low output of the dyna. Is that correct?

Thanks.

My opinion about "working well" is probably a bit different. I would
use a cartridge above 0.8mV output with that preamp. It can make life much
easier.
