You amp is severely underpowered for the speakers you have and those Sonus Fabers. You will find that a better match will radically improve bass performance. I would check out:
Zu Audio Soul Supreme - Killer speaker and very exciting/dynamic. Will be driven well by your amp.
Tekton - Not the most attractive speakers in the world but will deliver big sound for you. If you would like to read a positive review just look for any post by millercarbon.
Paradigm Prestige 95F- this will be bright like your B&Ws but technologically is a step forward and is a lovely speaker.
I am a dealer but have no affiliation with any of the brands mentioned. I personally would go with Zu but my hunch is you will like the Paradigms more aesthetically.
Good luck
