My tuner / amp requires a preamp, and I am not sure what preamp to buy. Most ones I see as either MM or MC compatible. Since B&O Cartridges are MMC, I do not know what to use. Please help.

It depends on budget too, there are preamps with both mm/mc settings. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
