Interesting thread. Have a similar rig with a Naia Aphelion2/SS Zephyr. I have looked at the Aric as well, but it has no adjustable settings, as far as I can see. For my taste, the Zephyr requires rather higher impedance around 1KOhm, while the Aphelion 2 is best at 100 Ohm. Both are MC and Aric recommends a switchable SUT. Zesto has a SUT with more levels of adjustments, which make quite a difference in my rig.
Sorry, don't have any recommendations, looking around myself. Plan on going to Vienna next year for some further inspiration. Zesto, Sutherland, and Rega have been on my list as well, but I am taking Pass off [have an XA25]. Currently have an EAT eglo petite, but not going to full eglo as EAT does not respond to customers inquiries at all.
