For what the SF Line 1 goes for that's a hard one to beat. The ModWright SWL 9.0 SE has a little better PRAT. Built quality on both are great. The remote on the SF does more; the MW remote only does the volume but it's a really nice sounding preamp that I used on many SS amps with no issues whatsoever. I've not heard a SS preamp new or used at that price point I'd pick over these two pieces.
There's a lot of very nice SS preamps but you'll have to spend a little more. The SF Line preamps really shine with NOS tubes so that can get a little costly. The SWL 9.0 SE only runs two 5687s and they're more affordable.
