This new Ayre QB-9 Twenty Upgrade looks very interesting. I wonder how it sounds.

I decided to sign up for this upgrade after speaking with Gary at Ayre. My confidence is high after successful upgrades to DSD status a few years back. Also, I had my AX-7 upgraded to "e" status and that also was a really nice increase in SQ.

If all goes well, my unit should be "Twenty"ed by late fall or early winter.
Wow, fantastic news.  I love my DSD but certainly would consider a Twenty upgrade.  Can't wait to hear some reviews!!

Thanks Ayre for keeping the QB-9 alive!
Anyone heard this yet?
Apparently there *are* units that have been upgraded, so someone has heard it by now. My unit is in the queue for next month, hope to have it back no later than December.
