+1 for yogi and mulvie. No self-respecting MM phono stage would offer only 28db gain, is an editorial opinion. But if you love it, and if your linestage doesn’t help enough, add an upfront gain stage. Not a SUT.

If you are considering the Marcof, I would really recommend the PPA2 over the PPA1. More load options,better parts.  Not sure but we may still have some new. I would have to get by Ed's, but I believe we a a couple 

If you're the patient type, keep a lookout for a used Herron VTPH-1MM. 44dB gain.

@mdrone 

The problem is that the Leben has abnormally low gain. Most MM phono stages offer around 40db of gain.

I have had the Leben in my system and quite frankly it is quite vague - not worth the money in my view. Even a cheapy Soundsmith phono at around $1k was significantly better. 

My suggestion would be to get another phono stage or if you have the Leben, sell it and use the money for another phono.

Did you discuss budget.

This versatile ModWright tube mm/mc was listed 4 days ago, plenty of gain (read the manual for facts). note: canadian dollars
