Looking for some advice please regarding K or S phono boards in my 82 for the Audio Technica AT-OC9XEN mc cartridge. Looking at the specifications below which board would suit it better or doesn’t it matter? I have both boards.
The NA5xx boards that can be found and used in the NAC52 are;
NA522 - MM cartridge input x 2
NA523S - Low Output MC Cartridge input (standard) x 2
NA523K - Low Output MC Cartridge input (for higher spec carts) x 2
NA523E - Medium Output MC Cartridge input (also seen as 523R) x 2
I had S in my 82 ( originally for an AT OC9) and then got a 52 that came with K. Ran that for a while until I got the 52 serviced and took that as an opportunity to get the boards swapped. As I was changing other things at the same time (moving house) I can’t comment on its specific contribution. But all combinations have sounded great!
