As a happy owner of the MBL 1621A transport, I'll say you can't go wrong with the MBL. Coupled to a nice DAC (like MBL's own DACs, they are fantastic at all price points) I strongly doubt you'll ever need a new Red Book front end.
The 1521+1511 combo is quite close to the 1621+1611. They basically sound the same but the 16xx's just goes that extra step. If you can't afford them, don't compare the two.. The 15xx combo is wonderful in its own right, and compares favorably to most other digital sources I've heard.
