Phono preamp, all suggestions welcome

I’ve tried a few in the under $500 range and none has been as quiet and detail oriented as the iFi Zen Phono. A $2K tube EAR is only slightly better/more engaging. 

This is a rabbit hole I went down recently as well. The widely diverse responses can be bewildering!  I ended up getting lucky and finding a black ice audio f159 for under $1,000….its wrapped under our tree so I’ve yet to hear it!!!  That said it’s a tube hybrid model and some of the reviews have me salivating for her debut. 
that said, I has close to pulling the trigger on a hagerman cornet (MM) or trumpet (MC), which are tube based.   

First of all I think you should reconsider your plan to replace your 2M Black.  To wit, I am currently comparing two phono stages, C-J TEA 1 series 3 and C-J 88, both very expensive (well above those you are considering), and one of the cartridges I am leaning on heavily to do so is the 2M SE, which is the 2M mono based on the Black.  My point is the 2M Black a very fine cartridge, well suited for use with any of the phono stages you are considering, and very near tops at it's price.

Next, are any of the units you are considering offered with return privileges?  If so, I strongly recommend that you start with those.  Given that all of the ones you mentioned have good reputations it really comes down to which one sounds best to you.
