If money is not a problem

First, I would start with designing state of the art room. Hire a pro for acoustic treatment, sound proofing, best frq. respond and have the top speaker designers come up with the wining design to suit my needs and taste. Have custom amps build to get the most out of my spekers. Possibly have the amp and speaker designer working together on this project. You said money is NOT A PROBLEM , right??? Well, there you go.

I'd have to worry about what sounded best on my yacht, jet and beach house too...wonder if I could hire Wilson audio?

Hello Mrjstark: My audio dealer told me someone in the SF Bay Area did just that. Cost him around 5 million.

I myself am a simple man..... probably B&W 802D provided I have the right surroundings i.e. no neighbors within listening range, detached house......

There's a guy who poured the concrete foundation of his listening room into 2 bass horns and mounted huge drivers into it. Claims -0 db down to 10 hz (I believe).

There's a blog and pictures somewhere out there, can't find it right now.

That's what I'd do first!
