I just bought a 2nd hand PS Audio Stellar Phono and was blown away. Compared to my MoFi StudioPhono (which is the best under $1k Phono Preamp around), the Stellar blew it away by a country mile. Understand though there are price points that each designer (Darren Myers/PS Audio & Tim De Paravicini/MoFi) had to work within. The StudioPhono is no slouch.
The Stellar by comparison is thicker sounding (which I prefer) and rivals my PS Audio DirectStream DAC Sr. for affection now I'm still a Digital Man but this Stellar Analog Kid is making me enjoy Vinyl again. PS Audio has a winner on its hands.
I just got back into Vinyl and am treading the Waters very carefully.
