Sonus Faber grand Piano sounds muddy????

I recently auditioned the SF Grand Pianos and for some reason they sounded muddy. It was like the bass was interfereing with the mids and highs? Has this happend to you?

i asked the dealer what his system was and they were using a Perraux 250 watt amp with a perraux pre amp and a rotel cd player. its either the set up or the acoustics. But the room was carpeted which I assumed would have absorbed the bass? I had super high hopes for these speakers but the Concerto's sounded much better. Much clearer.

What gives? Is the Grand Pianos really muddy?

Thanks
