new approach to hifi and a reality check

Yes, markets move on and mature.  In my view streaming is just beginning to reach maturity:

Gen 1:   Ad hoc streaming using systems assembled from computers and other generic parts (computer, NAS and external DAC using non-specialist software).

Gen 2:   Streaming hardware products using recognised protocols but with compromised performance - well implemented gen 1 systems still easily outperform these.

Gen 3:   Streaming hardware products with optimised performance; performance is essentially a match for well implemented gen 1 systems (this is where the Naim streamers came in and where the component systems still are).

Gen 4:   Streaming hardware products with increased flexibility and optimised usability (Naim's new Uniti series and products from other manufacturers in the last 2 or 3 years).

and I understand there might be interesting cross overs from the top end Uniti into the middle to possibly more top end Claasic - certainly from a listening session with a prototype Nova I can well believe it

You think it can drive speakers as well as a NAP200, with as much tolerance for varying speaker characteristics?  If so that's a remarkable achievement for a class D amp at that price level.

Many class D amps work well with some speakers and fail miserably with others in very unpredictable ways.  It's more than just a mismatch of sonic characteristics, some dynamic loads (aka speakers ) can sometimes seem to stop the amp settling properly, causing a whole collection of odd electronic behaviours.  Damping these modes to get stability also compromises the transient dynamic characteristics of the amp - hence requiring more complex (and more expensive) solutions.

There's a direct analogy to why it's so difficult to make current dumping amps sound good.

Uniti isn't Class D amplification though - they're all Class A/B...
