Ayre AX-5 Twenty.   Shockingly great sound.  

Whatever it is, Ayre designer is dead, I understand, and you don't want to buy this company, especially new.

I heard the AX-5 Twenty with Vandersteen Quatro Wood CT and QX-5 digital hub just recently in Santa Monica. Decent, but to me, not shockingly great at all. I know some really love this combo, but for me it lacked resolution and bandwidth; it was a little sharp and had no real snap or sparkle and that's not for me. I do respect others find it attractive though.

Yes, Charles Hansen passed on very recently. RIP and God bless his family.
