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

Approaching the 400 hour mark. I think the upgrade is settled in but someone on another forum posted that it needs 500+ hours to fully reveal its character.

My initial impression is unchanged although the Twenty does sound better now than cold out out the box. To my ears, in my system and room, the main improvements are 1) improved clarity and resolution and 2) an expanded, almost unbounded, soundstage. The overall effect brings a refined sound that makes it even easier to relax into the music. I always considered the DSD version be be excellent but the Twenty is a notable step up. 

The increased clarity makes it easier to hear individual voices and instruments during complex passages. The added resolution adds a bit more texture all around; performers and instruments are more “fleshy”. This is most obvious in the midrange but I also hear improvement in the bass and, to a lesser extent, the treble. Perhaps this is the result of even quieter backgrounds? Well recorded music is revealed on a more dimensional and defined soundstage. And there seems to be no aspect of performance that is a step backwards from the DSD version. Nice!

This could be my final equipment upgrade; retirement is on the horizon and it would take a LOT of money to significantly improve the sound my system is now giving me. Kudos to Ayre for upgrading a discontinued (?) product.
Frankly, Beetlemania, I don’t hear a wow factor in your appraisal of the upgrade. I’m not intending to sound overly negative but for $1,500 I’d have thought there would be a more noticeable improvement. 
@beetlemania Thanks! I did find your post on Audiophilestyle as well as the back and forth with Ryan. I've been pretty happy with my DSD as it was very close to the sound of my VdH Frog. However, a new tweak to the table and the Frog has gotten through the 100-hour break-in and I was starting to notice the QB-9 not being as engaging as before, though it is still extremely good. I'm putting the Twenty on my list. (And no, I don't ever expect digital to sound as good as vinyl, especially in my system.)

Thank You for the update. I will concur in that the Twenty Series is incredible to report the very least. Any difference or sonic improvement is not subtle.

Merry Christmas!
