If it were me, I would stay with tubes and get a Music Reference RM-200 Mk II. Rodger Modjeski designs are extremely reliable (I have a 35 year-old RM-5 preamp that works like new). Look at reviews in Stereophile. Cost is about $4200 new. The RM-200 delivers 100 wpc which is more than you are looking for, but the LS3/5A is pretty inefficient (82 db) and generally requires more than 50 watts despite it's small size.
I married the perfect woman. The downside is everything that goes wrong is my fault.

The high impedance of the LS3/5A compensates in some ways for its lack of sensitivity. If I use these speakers at my winter place, I drive it with an 8-9W 300B amp. The tonality is correct, but many people believe you need more power and a beefy power supply in terms of reserve capacity in the PS caps to get good dynamics on fast symphonic music.
Stay with tubes.Check out Quicksilver. Outstanding with any LS3/5A type speaker that I have owned!
