good hifi store in Bay Area

You should have no problem finding a good store in the Bay area.

It is doubtful a Magnolia would sell the Marantz higher end products but I am sure they could specially order it.

We just got in the Krell K300i intergrated you may want to check that out as a possible alternative to the Maranz.

The K300i  is $8k so similar in price to the Marantz, is 150 watts Class A and has a great built in dac and streaming, it also sounds really rich and very tube like, which should complement the detailed sound of the B&W Diamond tweeter which works well with richer amplifiers such as the Marantz. The digital board is really good sounding and has the ability to stream Tidal and is fully MQA compatible and the piece even includes Apt x blue tooth.

There is also a standard version without the streaming digital board for $7k.

Not sure about current brands, but here are my favorite stores in the area:

Music Lover's

and Audio Visions

Both are good shops neither sell B&W though we visted both shops a few months ago.

Looking at the Music Lover's Speaker line up they do sell the Paradigm Persona's. IMHO they have it all over the B&W's. At my dealers he had a very nice compact system for a small to Medium room. The Persona Monitors and the Naim Atom. Doesn't take up much room but a nice big detailed sound.

@hifineubee have you tried the dealer locator from B&W's web site? Sounds like you might be looking for a non-custom installer—you can filter them out in the dealer locator.
