Advice from Audiogon family - best speaker $3k-$4k

Same question as @soix , I would add that McIntosh has been known to sound very good with B&W's, a friend has that setup and it's a nice match up, so if you can, take a listen to some B&W's. Sonus Faber has a very good reputation,so nothing wrong there either.

I myself have had Mc and Bluseound equipment in the past, but have never owned B&W's. Just FYI.

I have listen to Sonus Faber and I like them.  Advice?

you've answered your own question, if you like them after hearing them, what advice do you need?

I am open to either new or used.  I currently own a pair of B&W 804 D3.  I like them a lot and they are paired with McIntosh and Levinson.  I live in Seattle.  We seem to have a limited variety in this price range.

Brooks Berdan is moving up to Seattle.

ProAc is a serious contender. When I went from Sonus Faber to ProAc (monitors) I never looked back. They are extremely dynamic, big soundstage, punchy, completely non-fatiguing, smooth. a DT8 will knock your socks off…good luck on your hunt!
