Would you trust a local dealer to help you put

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.

True, remember that a wise man learns from other's mistakes.
Actually I do have just that Rega system in my 13x11 den and it sounds VERY natural and captures both the dynamic range and low-level dynamics of the acoustic music I listen to.
In a big room I'd only need switch to RS-5's perhaps-there is a great synergy in a all Rega sytem, they know of what they do.
Don't tell the wife but on all but the largest symphonic works, I actually prefer it to my Belles/Maggy 3.6 rig in fsmily room.
The RS-3 is star on vocals,but probaly not a rockers dish which is irrelevant to me.
