I have heard Harbeth speakers at many audio shows and they always struck as kinda "meh", nothing that I fancied at all. Even if they were a quarter of their retail price, they wouldn't interest me. They are nice furniture, that I will admit. We likes what we likes, I guess.
I have built a couple of CSS Audio standpoint speakers -- the 1TD-X and latterly the smaller two-way Torii, which cost around $500 with the flat pack, and I could easily live with them as my reference speakers, although I do prefer my Cube Audio Jazzon speakers, but they cost $8,000. They offer pre-built speakers as well which are still an awesome bargain in the audio world.
