Well, I don't know if the digital amps have really come to its age. Yes, it does have an enormous potential especially with respect to size/cost reductions for a given power output. But my understanding is that the budget digital amps may still have some residual problems in S/N and distortions. The problem is, there are quite a few multi-grand high-end digital amps, as well as "microsystem"-level budget products, yet there are very few in-between yet!
That said, I've never seriously listened to the Sony S50ES or C70ES all-in-ones -- so if you liked them, I guess these may be a good value for you. They are definitely "new kids on the block," so if you are a new-gadget freak, and want to have everything compact, these may be attractive options.
But I would still listen to them first, with the Axioms or other speakers with equivalent resolutions. You might discover that these digital receivers don't quite deliver it yet...
