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.

I believe that is incorrect, @montesquieu. My 868L (line only) contains two 7DJ8 tubes, the 868PL (phono and line) contains an additional two 7DJ8's for RIAA amplification.

No I’m absolutely correct. The 868PL is a tube-FET hybrid along with the inductor in the phono stage (four tubes, two each section) the 912 has five tubes and an all tube + inductor phono stage. The phono sections are different designs.

To add, the SUT sections are different too, with four ratios rather than three ... though still marked 3, 6, (12) and 40 ohm the ratios in the 912 are higher, but can be attenuated 0, -6 and -12 dB via the intermediary transformer between phono and pre sections for even greater flexibility.

Not the same thing at all.

I (and Art Dudley & Robert Levi) stand corrected, montesquieu! Do both use transformers to create their balanced outputs?

Yes both use output transformers a tim de p speciality.
