Tubes or solid state for Sonus Faber Grand Piano

I own the Sonus Faber Grand Piano Domus Speakers and am using the McIntosh MA6900 Integrated amplifier (200 WPC). I have an opportunity to buy a McIntosh MA2275 Stereo Vacuum Tube Integrated Amplifier rated at 75 WPC. Will the GP Domus sound good with tubes? It has been my experience that the GP Domus requires high power to sound good and I am concerned at using 75 WPC. Will bass response be a problem with tubes? I noticed a huge sound difference when I switched from 50 WPC to 200 WPC. Please send me any comments and suggestions you have? Thanks..
