Is it possible to squeeze more out of the 16/44 format with a tubeoutput? 

I don´t think so , even with a very good quality tubeoutput analog stage (pre section) on a CD-DAC introduce too much coloration and distortion .

What I am looking for, in the context of solid state vs. tubeoutput, is difference:
  • In harmonic content, the nature of the harmonics
  • In dynamic tracking (especially small dynamics)
  • In imaging and ambience
  • And perhaps in a thing that is difficult to talk about; namely "presence" or "x factor" 
1. It depends on the output stage , if using a single ended or pp output stage for example and depending on the individual class of tubes used . 2. I think this is merit of the DAC chip itself .3. Imaging depends on too many things but not just tubes or solid state output .4. same as 3 .
I use too have tube outputs stage DACs ( really analogs sections) , I prefer solid state by far , but the topology must not introduce any harsh sound , must not introduce nfb , that kind of sound its not good .  so you need to find a really nice manofacturer with very good concepts , try to follow the concepts around dCS .
