I've owned an SLP-98 for maybe 10 years now & have been very happy with it. Using it with a SS CJ MF2500A amp. Personally I wouldn't call the SLP-98 particularly "tubey" sounding. Depends on what other preamps you're comparing it to of course.
I'd be interested in how it works out for you, with tube rolling, etc.
