In my case there will not only be two separate amplifiers for the two devices but also a dsp/dac, the ADAU1701 as suggested by Scott and a WiFi connectivity option along with a simple analog input and USB also. The network will be done in the dsp so nothing after the amplifiers so a direct connection. This allows for time alignment and FR correction. Now the best solution for volume and balance control are another factor to consider.
Yes, staying in the digital realm for as long as possible seems the most prudent. You'll still want to change the gain relative to the sensitivity of the respective drivers (as to achieve as much SNR as possible), but as far as integrated, that's about as good at it goes! Much more to be gained on the speaker side.
JC--aren't we all constrained in some fashion to our audio quality? Surely there's much to be said for diminishing returns. Speakers and room being dominant.

I will have two different power levels due to the very different efficiency of the cone driver and the dome tweeter so a 10 to 1 ratio is what I am looking at. Each amplifier will have plenty of overhead so they should never clip before you've reached the max output from the speakers. The major development has actually been on the speaker side so the goal is just to not diminish the sound quality with the electronics rather than the opposite which is the norm.
Depends what you mean by compromise. Will I buy and amplifier 10x the size I need in case I one day buy a pair of speakers that are very badly designed? Nope.
If I only need 50W per driver why not use the best 50W amp I can get rather than a 400W metal monster?
True.
Furthermore, this would allow one to design amps specifically for their place in the system, like using pure class A operation for the tweeter and possibly the midrange, as both will require relatively small power outputs, since the crossover will not be of the passive, but of the active type. Passive crossovers gobble up up a lot of power.

Depends on the definition of "quality." Different market segments have different design goals. If you mean "actual sound," yes, this is generally true. If you mean "ability to impress a chimp reviewer who peeks," perhaps not.
😀 Or, my speakers are bigger than yours...
Headroom... Do I need to raise my ceiling? That's certainly a link between size and quality...
It's a semi-serious question. we all know that some amplifiers really don't recover well from clippping, others shrug it off. With high GNFB really odd things can happen. So setting amplifier power such that you always have 8-10dB headroom might seem a good thing. Or arrange things so 0dBFS is below clipping.
Of course with Vinyl its a lot harder as no specs for modulation and those pesky pops and ticks. People want huge overload headroom in the phono amp, but there is no limiter downstream...

Speakers are a bit different in that there really can be advantages to more cubic inches. But indeed, we get influenced by visualizing their size as well- see Toole and Olive's work on this.
Absolutely, and indeed vinyl can vary a lot.
I have a Todd Rundgren album that's 76 minutes long... Nothing very peaky in that! That's a case where the CD is sooo much better!
But for digital sources, headroom is straightforward...
A 12fl oz Minute Maid can contains as much orange juice as 3 pints of freshly pressed.
Doesn't make a frozen can in the freezer an equivalent or superior.
