I had an SLP98 years ago after they first came out. Maybe they have gotten better over time with upgrades, but to my ears that was a very colored preamp with not much transparency. I sold it to a friend of mine and purchased another Modulus 3a.
You should also consider the Don Sachs Model 2 preamp. Plenty of tube goodness and very transparent too.
