@knollbrent If you're not getting enough gain through your Mac phono preamp, then I suggest you try through at least a couple of other standard phono preamps. What that will tell you is if your cartridge just has an unusually low output or if your Mac phono preamp is defective in some way. Questions:
Have you tried to play a different phono cartridge through your Mac phono preamp?
Have you written to the cartridge manufacturer and explained your situation to them?
Is it possible that you have a defective or otherwise not properly operating cartridge?
Is it possible that the Mac phono stage is not operating properly? Could there be a bad tube in there?
I'd do more research on this before you conclude that you need a new phono preamp. I've never heard of a MM cartridge that had such a low output. Something somewhere is most likely just not operating properly.
