a word to the wise
On the "what is special about Harbeth?" question, here’s part of my answer.
Having auditioned an insane amount of speakers - the Harbeth have just stuck out in terms of being able to produce the "gestalt" of the human voice, as well as acoustic instruments. But human voice in particular.
@prof, who stated the above, has contributed perhaps the seminal thread here on his hearing and assessing a whole host of excellent, mid to upper tier loudspeakers - for all interested, especially relative newbies, i strongly suggest you use the search function, or click @prof to see his past posts, and find that lengthy, but exceptionally broad reaching, informative thread - the value of this forum is only in small part the live threads, it is what has been written, covered and discussed in the past...
for others, who might feel a pair of used harbeths for under 2 grand is a poor value, well, neither @prof’s wonderful thread, nor i, can help you much... there is always youtube...
