Would you trust a local dealer to help you put

Even if I trusted the dealer, I'm not sure their sonic choices would necessarily be mine. Add to that, few dealers carrying everything- they will be constrained by the brands they represent. So, I wouldn't do it, although I'd certainly listen to what a dealer recommended as a system at a given price point and decide for myself.

If you can decide on speakers then you could post here for recomendations. Ask for recomended electronics with synergery to your prefered speakers. That would be a start

a dealer can tell you what you like. there is no substitute for experimentation.

After 40 years I now know that speakers only let you know what your amp sounds like. In a 10K system I'd spend at least half on amp.

If I had any sense I'd buy a Rega Brio-R intergated,Rega Apollo CD and a pr of Rega RS3 speaker with DNM Reson wire
for about 3k and be done with it.
Thats at least 85% of whats possible and thats from someone
who has spent at leasr 150K over the years.

Tennis- I think you meant 'can't.'
Schubert- yes, there is something appealing about that, including the idea
of an integrated amp today when, 20 years ago, it would likely have been a
compromise. I suspect though, that you are only at the point where you are
now, having been through the thoroughbred stuff. It's sort of like seeing the
appeal of a Dino 246- not a macho car, but after you've had your share of
those, you get the idea of its beauty and its limitations are far more in
proportion to real world driving than a modern-ish supercar.
