Bowers & Wilkins 801D4 Signature

If you like the sound, maybe the price diff is worth it

I have heard both, and thinking about moving to the regular version from my Audiovector R3, I did hear a difference, but not enough to make up for the price in my opinion. Now, that could have been because the regular was driven by a Classe delta stereo, my current amp, and the signature was driven by pass labs, can’t remember the model. But I generally don’t like pass labs. 
 

(it was at a dealer and it was in two different rooms.)

It is critical to know whose signature. If it’s MJ’s signature then by all means go for it.

@fredrik222 Those Audiovector R3 sound really good for their price.  I enjoyed them at a couple of shows and been impressed each time.

According to the manufacturer they are definitely different, significant upgrades in the tweeter, crossover, the plinth, etc.
