I have had nothing but great experiences with Bloom audio, located just outside Philly. You can set up a demo of any product(s) if you’re in the area, if not, they include overnight shipping for orders over $500 (I think). They offer great support and have always been super responsive by phone and email, even if it’s a non-purchase related question. 10/10

Their YouTube reviews of specific products are good as well.
