Got my old ayre qb back, now labelled as „twenty“. To make it short: if you have an old qb dsd or qb whatever do the upgrade! Highly recommend!!
Interesting. I rather like the Ayre QB 9 DSD. What do they do to it to make it a QB 20?
hi Richard,
they replaced everything except the housing and power- found this picture on web>
right is the new one!
Takes a long time to burn-in but now it really opens up…
Great VFM option.
