What a shame.
Until 2020, a pair of N804 was the main speakers in my media room, and a pair of N805 was the main speakers in my office. I purchased both in 2000 or 2001. I thoroughly enjoyed them for almost 20 years. But, any time I heard newer B&Ws over the period, I thought something was seriously wrong with them due to the obvious hole in the mids and overly present sizzle--even up to the flagships.
My adult son recently purchased a pair of 685 S2 speakers after reading the WhatHiFi review and experiencing my B&Ws for most of his life. Absolutely terrible. I gifted him my "vintage" B&Ws, since he grew up with them and is attached to them. That is a good outcome for them and him, methinks. My pursuit of replacements ended with Revels and BMRs.
B&W once built great speakers for their time, but they have clearly abandoned that pursuit. They have the knowledge and technology, but their priorities are elsewhere.
