My SLP98P is an F1, with custom paint and upgraded MC phono stage. I bought it from Kevin about 15 months ago. It's a great preamp, but I'm not real sure about the phono stage. I mean it is nice, but not great, IMHO. I have downsized quite a bit in the last few years, and overall I am pretty happy with the sound of my rig, but I think the built in phono stage may be my weak link right now.
One of these days I want to get around to trying a nice separate phono stage, like a Herron VTPH-1 MC plus, to see if I can do better. I'm very happy with the line stage though.
FWIW, I have my SLP98P paired with a VAC PA 35/35, a 35 wpc triode EL34 tube amp.
