Iv'e had several friends with Sonus Faber speakers , and to make thinks sound right they both had to go to solid state amps . I can't say why this is , but I have found that all Sonus Faber speakers Iv'e heard had an excellent but slightly soft warm sound , tube amps seem to have the same virtue . Maybe to much of a good thing ? On the other hand I can't imagine the Lamms sounding bad in any system , weather they can power your speakers properly will in part depend how loud you want to go . How loud do you want to go ? Good luck .
