"What research I have been able to do leads me to consider opening up the
sound stage with something more mixed, like a conrad johnson pv14L as
pre- and the ayre v5xe, and coming forward in the age of digital,
considering something like the oppo 105 but i was also thinking the nad
m50 / m52 combo instead of the oppo..........and lastly all this heard
through (I'm thinking) vienna accoustics beethoven baby grands"
You need to build a system, not buy a bunch of separate components. I definately wouldn't put the V-5 and the PV14 in the same system. As for the other components, they're OK by themselves, but mixed is just too random.
If you match your components correctly, you'll get much better sound for a lot less money. Here's a system for an example of what I'm talking about.
Source - Ayre Codex
Amp/Preamp - Ayre AX-7 integrated
Speakers - Vandersteen Model 1's
You can spend a lot more on the components you list, but if you compare them to this simple system, they won't even stand a chance. It wouldn't be a fair comparison. Those components sound greater than the sum of their parts because they're working together. If you went about this in a different way, you'll have to spend 3-4x the money to get equivelant SQ.
