MF A308 vs A5 cdp

Hello people!

Has anybody ever compared these two cd players?
the A308 looks more robust and more sofisticated in the circut layout (with chop regulation), on the other habd the A5 has tubes in the output stage and it should be the "best cd player ever made" (...).

I own the A308 integrated amp and the A5 CD. Quite happy with the combo but I am tempted to get the A308 CD to match with the amplifier...

hope to hear from you!!
