No, the signal is not digital when it reaches the speakers unless the speakers have built-in D/A converters to convert the signal back to a useable analog form. There may be a few speakers like that on the market (maybe Snell, Meridian, etc.) but my guess is that the amp has to convert the signal back to analog before it gets to the speaker or your system will pretty much sound like a fax-machine's data stream. And I can't listen to that very long. :) It has to be converted back to analog somewhere for you to hear it as "music".
My guess is that such an "all-digital" system (using currently available technology) will not be the eargasm you might think. There will be almost no euphony and the sound will likely lean toward the clinical or dry. I doubt that you would characterize it as "sweet". And what about adding an analog source, I mean, if you wanted to?
Of course I could be wrong. This is only my best guess as I haven't heard such a system myself. It sounds good in theory but in actual practice I'm not so sure it would live up to the hype...
That said, the amps you've mentioned are supposed to be very good sounding units. If you bought it and found you needed more of what analog delivers then you could always add the analog somewhere upstream. As I see it, there's not much risk in trying it. Perhaps others have done this and will write in with their impressions...
Then again, some things will sound quite good -- at least until you make a comparison to something better.
