MBL 1621 vs 1621A...sonic differences?

Has anyone compared the MBL 1621, now deleted transport, with the present 1621A?
Hi Lula,

The 1621A across the board sonicly out performs the older 1621 transport. MBL will not come out with a new generation unless they believe it will out perform the older piece. I own the 1621A and it is a better sounding transport then the 1621. I still think the 1621A is the best sounding redbook CD transport, even better than the great sounding CEC-0X.
