@drambuiequillhill Thanks for posting this. I recently got the Naia package and also wonder about suitable phono stage. I currently have an EAT eglow petite with a Zesto SUT, which makes a more full bodied sound.
@jcoehler Re the REGA Aura, it is MC only, so not suitable for use with SUTs. I also find the load selection only up tp 400 Ohm rather low. With my old rig with a SoundSmith Zephyr MIMC* cart, it sounded best with a 1000 Ohm load. The Aphelion does sound best at around 100 Ohm. Ditto also for only 2 gain settings.
The Aura may be good if one wants to stay in Rega's walled garden. But for a bit more exploration, it may be rather limiting.
Looking for other suggestions: Sutherland, Manly, PrimaLuna, Zesto, PassLabs...? With "rule" of PS cost = half of TT, I would want to stay in the $5-10K-ish range.
