I daresay if spent wisely you could upgrade your amp AND your speakers for $7K. Perhaps something like this:

And since you like Vandersteen you could do this:

And these which as an Audio Note owner I can highly recommend:

That was a fun exercise that took just a few minutes poking around the site, obviously just a few things I like our tastes may differ. My best advice would be take your time, do research, listen if you can, and try to buy once and buy right. Good luck!
