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.

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
Thöress Integrated “Super” Preamplifier ... a versatile full-function tube preamplifier incorporating a state-of-the-art line control amplifier and a ground-breaking phono stage in one case. 

Just to correct a mistake above, the phono sections in the EAR 868P  preamplifier and 88PB phono stage are valve + FET designs, whereas the one in the  EAR 912 is all valve. All are so-called LCR designs which use an inductor rather than relying on series resistors and capacitors for RIAA correction, but the 912 does not use the same phono stage as the other two.There's a lot of misinformation out there on this but a look inside the box settles it.
