alaindexe OPGreat way that will sound very good, would be a $799 Schiit Aegir 20w Class-A for the highs and a $699 Schiit Vidar 100w a/b for the bass, horizontally bi-amped. Which if you look at the Altec xover is a snack to do.
Suggestion for a SS class AB amp that sounds like a class A ... if such a thing exists

You will need though a Schiit $49 Sys passive on the Vidar input as it has more gain than the Aegir and needs to be lowered just a bit, and this will allow you to tune the sound a little to your room or yourself.
