Sonus Faber Grand Piano vs. ProAc 2.5 Speakers

I am considering "consolidating" my two audio systems into one and cannot decide what speakers to keep. I own the Sonus Faber Grand Piano [older model](with the Bow Wazoo integrated amp) and the Pro Ac 2.5 Speakers (Jeff Rowland Concentra amp). The source is the Meridian 508.24. I prefer the Sonus Faber speakers since they just sound better but, of course, I have to ask others for comments. The ProAc's have more bass but do not have the musical feeling that the Sonus Fabers have. I also should consider switching the amps around to see what these does to the sound. Any comments on the amplifiers? Thanks...
