Rowland/ProAc 2.5 vs. Sonus Faber Amp/GP

Jeff Rowland Concentra Integrated & ProAc 2.5 Speaker vs. Sonus Faber Musica Integrated amplifier & Sonus Faber Concento Grand Piano Speaker? Heard both, Sonus Faber sound very soft, open, musical, seems to disappear in the space and the Rowland/ProAc seems more real, less colored, more bass and more balanced (true) to the music. The Rowland/ProAc seems to be more realistic and music like than the Sonus Faber combination. Speaker placement on both were very critical as small changes impacted the sound. Current thinking is the Rowland/ProAc 2.5 because my sense is it presents the music better, is less colored than the Grand Piano and is more real to my ears (but the Sonus Faber combination also sounded good). This is not an easy decision and I need some opinions one way or the other. Comments and advise welcomed.
