Replacing my MFA Luminescence B2 preamp

I have in the past year returned to high end audio after a ten year lapse. I just got my JC Verdier La Platine TT out, purchased a brand new ZYX Ultimate 100 mounted on a 25 year old SME V. The only other source equipment is a Wadia 16 of 1990’s (?) vintage. Amplification is through Von Gaylord / Legend Audio mono block amp.  I dug out an old pair of Morel MLP 202 bookshelf speaker. And I started playing music through my thirty year old MFA Luminescence preamp.  ( I know, It’s an eclectic mix ! )

My question has to do with the preamp. It’s a vintage piece of gear, apparently still sought after.  But I am decidedly not technically oriented. Every so often, it requires maintenance. As I write this, it is sitting in a shop, because the phono section works only in one channel. MFA Luminescence is brilliant in action, but it’s the down time that has me thinking I should move to a simpler setup. I wonder if moving to a Coincident Phono preamp might not be the answer? It fits my set up of  only two source equipments. Would it be a step down? Any other options?

please help!
