The M40.2s are unquestionably the best Harbeths in my opinion, but for their price, I simply don’t understand the appeal.
The 40.2s retailed for a smidge under $20k, but I don't think anyone paid that amount for them. Mostly they were selling for around $16-18K. I see that the 40.3s are now touching $25K retail, and I would tend to agree with you that they're definitely not worth that much. Same for P3esr's -- too expensive given the competition nowadays.
However, I would add that Harbeth is one brand that has to be experienced in your own system to understand what it's trying to do. Simply listening to it at an audio show never reveals the special sauce. As I mentioned, I owned the Joseph Audio Perspective2 Graphenes and loved them. But the Harbeth still gives me better timber, tone, and midrange. The Jospeh Audio are certainly a more modern, crisp sounding speaker, and I can completely understand why some people might prefer it.
