EAR vs Audio Note preamp


Friends,
I am contemplating getting a preamp with in-built high quality phono stage. I have shortlisted EAR 868/912 or Audio Note M3/M5 phono. I plan to buy pre-owned so I am flexible about the models. The power amp that will be driven will be a Nelson Pass First Watt F6 initially and slowly I may get into the SET domain. Can someone tell me about the sonic difference between EAR and Audio Note preamps ? I value speed, dynamics and purity of tone. I am neither for artificial warmth or artificial clarity.

Do you have a budget?

If you are considering an ARC Ref 5 maybe that's a dumb question... you do know that the ARC doesn't have a phono section, right?

I'm puzzled how it boiled down to these choices. Some others to consider: the CAT Signature, cj ART, perhaps the Cary SLP-05 all of which have good phono sections. I like to think we make good preamps too.
Ralph, if I go with ARC then I will get their Ref phono 2 too, it all still comes down to well within $15k (used) which is affordable
Speaking of Atma-Sphere pani, don't overlook Ralph's two full pre-amps. They're REAL good, and rather than discontinuing and replacing them every couple of years (ala ARC), he instead offers current owners updates. A MUCH better deal for owners, and a more honorable business model imo.
Unfortunately in the region I stay (Singapore) Atma-Sphere has very little presence. No dealers here, hardly anyone has any experience to share. So, it is a total shot in the blind for me. Else I would love to try a OTL tube preamp
