if you are talking about Sumiko Blackbird, that is a high putput Moving Coil cartridge and not an MM. Try different settings and see which one sounds best. Loading is important too.
Pro-ject Tube Box SEII setting with Blackbird cart
Any advise on how to set the SEII with the Blackbird? The SEII accepts both MM and MC and I have been told to use the MM setting for the high output BB which is of course an MM cart. Just wondering if anyone has done this and how does it sound. My SEII is on the way to me and will arrive next week.
