I've never heard the Little Loco but having heard other Sutherland phonos, I'm sure it's very good.
But if I owned the Naia/Aphelion 2, I'd stop at the Rega Aura. I own the P10/Aphelion 2. I tried the Rega Aria, then a Zesto Andros II, and finally the Aura.
The Rega synergy cannot be replicated with another phono when you are at the level you are. The Aura and Aphelion 2 are such an outstanding pairing.
That's only my opinion and experience.
