Boutique or Big Brand?

Big brands tend to give you more for you money sometimes. 
 

look at the build quality of the 800 series. It is outstanding, a small brand would be twice as much. I don’t like the sound of B&W but there is no denying the 800 have an amazing build quality.
 

 Then there are brands like revel. A true engineering powerhouse with real double blind testing. Their “cheap” 226be is simple great at $7000 I would put them up agents the focal Sopra line at 3 times the price. Is the Sopra better… yeah probably as it sounds more open but they are so close it might blow your mind at the price difference.
 

then brands like Sonus Faber look simply stunning. Wow, that finish would be crazy expensive from a smaller brand. They sound good too. 
 

so for me I would look at Revel, Sonus Faber or similar brand (too many to name) and if you don’t like the sound of those expand to other smaller brands. These two brands offer a lot for the money.  Used Olympica III are a great buy right now. Revel’s used prices seem a touch high to me but new they are a good deal.
 

lots of used Wilson out there too. Way over priced new but used probably ok and they hold their value.  

Nothing wrong with wanting/liking the 805d3. I have heard them a bunch of times and they are fine just a bit bright. Depending on your age a bit of brightness could be good but they are bright enough that bad recordings will be real hard to listen too. Make sure you give them a long listen with the actual music you listen to not just perfect demo music.

Where something like the Revel 226be has near perfect measurements. Their bass extension is light and the -3 db point is 56hz, -10db 36hz so should be fine in your small room which will bring up the sub bass through room gain assuming they are 24” or less from the wall. Not pushing revel just one example of a better speaker for the same money that I have experience with. There are tons of other brands too.

anyway I have owned both brands (B&W, Revel, focal, Thiel, paradigm, Klipsch… etc, ) I think you will end up fighting the B&Ws to sound good. Always tweaking toe in, gear etc where the revels are just a plop and drop and sound great as measurements matter. 
 

If you don’t have dealers music direct has 60 day home trials and free returns I think but read the details. 
 

as for buying used. If it is expensive enough for you wait until you can drive and pick them up or get a one way flight and drive them home. U-haul rentals are cheap, Just get a van. 
 

One more sound demo of the B&W 805d3 with the same Focal Sopra 1, different electronics.
