Do it! You will not regret it. As most all CD's players go, and especially the Cary 306 series, it needs a good amount of break in time to fully open up. BUT, once it does, it is the most musical, natural digital source I have heard.
This unit provides greater depth and sound stage as well as further resolution without any hints of harshness or brittleness.
I have spent quite bit of time with both the 805c and the 805 AE. In my opinion, the Anniversary Edition is by far the way to go. They have a much smoother presentation and are fairly more musical due to the front end redesign.
You would be surprised at what rolling the 300B's will do in these amps! If the money is available, I would recommend experimenting with both. However, if funds are somewhat limited, get the 845B tube from Shuguang it is I believe. This is an internally damped tube that uses metal arms that come up from the base of the tube to dampen the plate, completely seperating it from the glass whereas the standard 845 uses mica plates that keep the plate in place by resting against the glass.
