Naim NA322 or 323 on a N91ED?

[38628]

Hi, long time i didnt posted here.
I am getting out of dust my Naim set-up mated to my class D amp, and a Technics SL-2000 with a Shure N91ED with a "Hi-Track" needle.

I am just not sure what MC boards i should use in the Naim preamp NAC .32, the 322 or the 323 ? the 323 has the 470R and the 6N8 cap, that all i know, sounds like S boards...

thanks for any helps !!

want to listen to my old lp's....

The Shure is a moving magnet cartridge so you need to use the NA322 cards.

thanks for the reply. i found out why i was not able to find by test which one was the good one with some listening test, both sounded awfull, the 322 had bad 47uf caps, the brown encapsulated ones, cracked.
once replaced with some generic ones i had for the test they sound "ok", maybe a bit flat.

thanks again.

One of those 47uf caps is the feedback cap. It needs to be a good quality cap or the sound quality will suffer. I've tried Elna Silmics and found them to be a good choice.

Of course your cartridge is probably past its sell by date, the stylus at least?
