As others will no doubt say, this is very far from the ideal way of buying expensive loudspeakers.
That being said, if it's any help, I listed to Liutos and VA Beethoven Baby Grands in same room with same equipment. It was a close run thing, but ultimately I preferred the VAs. I liked their overall musical presentation better, though the Liutos did better bass. Personally, against the Mozarts, and assuming that these are a scaled down version of the BBGs, I'd take the Liutos, because of the bass.
