An Ayre AX-7 would be a big upgrade from what you have now. If you needed a lot of power the MF would be an OK choice. For SQ though, I feel the Ayre is much better. The new MF gear made outside the UK just doesn't sound like their old stuff.
Your speakers sound good with tubes, as well. Maybe look at a Rogue integrated. Excellent sound for the money and made in the US.
