Bowers & Wilkins 801D4 Signature

Can you recommend a home in Switzerland for my summer holidays?

Would love to see a picture of your System and your place in Brazil? What amplifiers do you use for your speakers. I have the MC 901 monos here

I like the B&w 802 d3 which I biamp now. Really need tubes for the mid and tweeters, especially with B&w.

Either are lovely speakers, but there is minuscule difference between the two in most circumstances.  I have the 800D3 I bought used here for $19K that I couple with Classe Delta monos.  I auditioned the 801D4 and was never quite sure if I could tell the difference.  Hence why I am working on room treatment.

At some point, it becomes a purely subjective decision, which is where I strive to save a ton of money by buying demos or lightly used.

I would encourage some tubes somewhere in the system as the mid and top end of the 800s is very precise and some people can find it tiresome.  I opted for a PrimaLuna EVO 400 preamp, but there are plenty of valid choices.

Long way of saying, any of the choices you are looking at are great, so I'd look for a set that someone is selling for whatever reason and go sink the money into the rest of your system.

I say, If you can afford the upgrade, don't even think about it, trust your dealer and go with the upgrade.  There's a good chance that your dealer knows what he's talking about.  In the long-run, you'll regret not buying the better speaker. 

Pleads listen to the Vandersteen Kinta at about 35k. They may change your mind. I went from B&W to their Quatro wood ct for about $17k.  Much better 

The Vandy Kèntos are pretty amazing. What Richard has done with his patented bass at this price range is crazy. They are worth an audition.
