Are Bowers and Wilkins speakers overpriced?

Reading all the 800 series posts has me drooling.  I have a pair of 792 S2’s paired with a Naim Uniti Star with Naim Naca 5 speaker cables and absolutely love them!!! I’m sure a pair of 800 series speakers would only be even more incredible and certainly their more curved nature are beautiful.  For the money though, the 702 S2’s are worth every penny.  Some dis the 700 Series for not being made in England, but they sound incredible nonetheless!!

dsper - They are overpriced because the tweeters are fatiguing

This is the most common complaint I have read about on many speakers. It is important to understand how any speaker was designed and tested (the type of room that was used, and associated gear ) - compared to the room and gear in which speakers are planned to be used.

Some audiophiles like to play roulette with their speakers; keep bringing in different ones, keeping the room and gear the same. Hoping to get a match.

I think the better approach when the high frequencies are fatiguing is to do one of two things.

1) Turn down the treble, or, 2) Turn up the bass.

You need equilibrium and both can be done by speaker room/angle positioning, different amps/preamps, etc...

Just angling the speakers outward a little may be all that is needed.

.

Many audiophiles do not incorporate an EQ in their system so just adjusting the highs and lows is not an option. 

I wasn't referring to EQ. Turning down the treble, or turning up the bass is done first by speaker/room mods/angle positioning. If after that its still not working, look into appropriate gear (amps/preamps)  etc...

Many try to run B&W with amps that can't do 4 ohms well. Look at the amp's specs. The amps struggle and you get lean sound output - which makes the Highs dominant and fatiguing.     

.....and at the listener end. Your ears need to be the close to the same horizontal level as the midrange/tweeter. 
Raise/Lower speaker height or get a proper height chair.
