Odyssey Khartago and Vandersteen 2

Upgrading to Sig. II sounds like the best option. Maybe I can get $4-500 for my speakers.

Yes, they're internally bi-wired. I have two runs of Audioquest Slate I can use. I'm using the internal bi-wire for convenience, I'm in a wheelchair.

Someone told me to get rid of the YBA stuff and look at an Ayre AX-7 integrated, it's suppose to work good with Vandersteens.

I have Vandersteen 3A Sigs with Kimber 12TC true bi-wire. I've heard the Ayre with Vandersteen and it's a great combo for sure. Check out the review of the Ayre Integrated in latest Stereophile. For my Vandersteens I'm using Red Dragon M-500 mono block Class D amps with ARC SP 16 preamp. Gobs of power, great sound, reasonably priced.

One day I'd like to try the Ayre gear though.

In my opinion, the best solid state option for Vandersteen is Ayre. There are other good matches, as well, but I like Ayre the best. You should have no problems driving the 2's with the Ayre 7 as long as you don't have a really big room. As for the results, I think you'll be very suprised. Everyone who hears my 2's with Ayre sits in disbelief. I think you'll be happy.
