First, a decent dealer would accommodate you by delivering and installing the amps. Especially at your budget.
Second, I would be leery of Class D. I tried them and though they sounded good, they just didn’t sparkle- though the bass was excellent.
Third, I am an Ayre fan and the VX is a pretty old model. I would go with a newer model. I bet even an AX7e Integrated would work for your speakers.
I would also look into Belles amps. I use their monoblocks with my Vandersteen VLR's. They aren't heavy and have more than enough power.
