I own a pair of the Bowers & Wilkins 805 D4, and I know what you mean about the brightness.
I think the sound you're looking for is British. I'd look at Harbeth or Spendor. However I've got a pair of Tannoy Eaton's I absolutely love that might work for you, and Upscale Audio has a sale on Tannoy.
Standmount speaker suggestion
HI
I have B&W 705 s3 Signature speakers paired with a Pass Labs INT-60. While imaging and soundstage are great, I find the speakers a bit bright. What should I try next, and what would be worthy of being mated to the Pass integrated? I will buy used but keeping in line with the value of the amp, the budget is around $5000- $8000 new.
I realize speakers are very subjective. Just want some direction to go.
Appreciate it.
