Which Phono Preamp?

None of those.
Get the vdH Grail SB and run your TT fully balanced into it and through the rest of the system.
This is at least the equal of all other high-end phonos and hardly known to anyone here.
Borrow one and try it at home.  I did and that's my only connection with the brand, save having bought four vdH cartridges. 

@jigasp            So you're 'getting the Herron'.  Only a day has gone by since MC posted.  No down on him on this one, it may be a good recommendation, but you mean you're going to buy it without listening first on your own rig in your own room???

That would be madness.  Don't choose any component on one recommendation without hearing it.  Not even a coloured fuse.
Unless you're an MC disciple who just likes what he likes.
