Reproducing the full scale, impact and envelopment of a full symphony orchestra in any domestic environment with any combination of hifi gear regardless of cost is out of reach. And it's going to stay that way.
Okay, sure. I know no one for whom this is a goal or an expectation -- at least on this forum. Reproduction is not reality.
But the real thing is in a hall with ~100 +/- musicians playing what you want to hear.
There we go. That's a reference for me. I'm happy if my stereo evokes that listening experience in a natural way. The music does the rest.
