I am literally frightened to listen to the Harbeth, I could probably afford them though with the $AUD exchange rate they are very, very expensive in my view, but that said I fear listening to them would make me buy them.
My favorite kind of speaker is the sealed bookshelf. My high end speakers are Axis Voicebox S and the emphasis on their design by John Reilly and Brad Serhan was to produce a contemporary LS3/5a inasmuch the overriding principle was "if you get voices right, the rest will follow". They are a small bass-reflex design with a very well integrated ribbon tweeter and the mid-range is excellent. I got them as ex-demo at a Christian price and is the most significant amount of money I have spent on hi-fi ever.
The Harbeths are a price jump for me that I can't really contemplate and I refuse to put myself in the situation of being tempted.
I briefly heard a pair at a social occasion playing in the background but that is a while ago and I have assiduously avoided hearing them again because for that brief few moments I knew that was the sound I had been looking for.
Can I ask Art K. what do the Harbeths provide that is missing in the LS50's, is it something specific that is quantifiable or is it something more encompassing than a particular parameter?
Congrats on the purchase, what finish did you select?
