Advice for Neophyte Assembling a System

If you like Sabrina's then you should like Vandersteen.
Unlike Wilson, Vandersteen's are time and phase aligned and are very easy to drive.
The Pass amp mentioned offers a lot more power than conventional amps-Mr. Pass usually underrates them.
Wilson's are known to be difficult to drive speakers (though newer models seem to be less so). 
I just looked at the specs and Wilson recommends 50 wpc. which seems reasonable. I think any speaker you get will need at least that amount.
The more power available, the more headroom for transients and little things that give music its' 'sparkle'.

From what you posted, I would also look into room treatment.
Glass is one of the worst things for music-highly reflective.

My 2 cents...
Look at lots of different speakers and find the characteristics you like.
Then narrow it down and make a decision.
After that, deciding on amps, preamps and sources will fall into place.

Lastly, where are you located? Any dealers near you?

The first, and by far the most important advice I can give is to go out and listen. A lot. To as much as you can. The budget you've got, anything less than stellar blow your mind results ought to be considered total failure. In fact, scratch that. Not just yours. Everyone's. Seriously.

Because quite honestly the results people get depend a whole lot less on budget than time invested listening, auditioning, and learning. There's hardly even any correlation between money spent and results. There's a system right here in Seattle, $1.3M worth of absolute train wreck dreck, stands testament to the futility of throwing money at the problem.

The second most important, which if you really take the first to heart you will discover on your own, but its worth making explicit: you absolutely must budget significant funds for tweaks. Power cords, speaker cables, interconnects, power line conditioner, fuses, room and component treatments like HFT, ECT, and so on. By significant I mean it wouldn't be excessive at all for half the budget to go into these.

Listen, learn, audition. Repeat. Patience is a virtue. The flashy big ticket components everyone already has dangling in front of you, you have no way of knowing now what a total distraction it is. And they are.

There's some general rules. You'll get better results with records than CDs, with tubes than transistors, and with integrateds than separates. You'll get way better results with two speakers and a Swarm than the traditional sub approach. But really its that first rule. Go and listen. 

Well ....
For the music you like, have you thought about vintage or reproduction horns?  You could get plenty of output, use a smaller integrated, possibly tubed, and have plenty left over for room treatment and power.

Think room treatments. Glass needs to be tamed. 

Thank you all for the great advice. Very much appreciate it. Bob, I am in Dallas and have visited our sole high-end dealer on several occasions. I agree there is no substitute for auditioning components. Unfortunately, the local dealer doesn’t seem that interested in helping.  The glass sides of the room has fabric shades so hopefully they will help mute the effect of the glass. Thanks again for taking the time to answer.
