Exotic veneer or high end automotive finish is obviously bling.
But does finish account for a high percentage of costs on luxury speakers? I dunno. 10 v. 2 bucks per sf. of veneer doesn't add up to much.
A lot of stuff that kinda feels bling-y, like the multi-piece cabinets on the big Wilsons, is of course supposed to positively influence sonics.
Since Maggie's have been mentioned, interesting to note they are relatively low bling free - a sock is a sock 😊 - and their flagship model is much less expensive than many luxury speakers to which it might be compared.
