Of all the speakers I have owned, I feel that Harbeths were the least fussy when it came to amplifier pairing. (Another way of saying this: Harbeths are less transparent to the source than other speakers I have owned.) So perhaps there is some truth beyond salesmanship to Alan Shaw's comment.
May I ask what amplifiers have you used with the Harbeths? I have used half a dozen amps on the Harbeths and they always managed to take on a different character with each and every one of them, and the differences are not subtle. Although the Harbeths may not be as fussy as other higher-end speakers, I feel they are equally transparent and sensitive towards upstream components. The Pinkfish moderator Tony who has owned the SHL5 for a short period concurred that the Harbeths are not only critical towards setup and placement but upstream components as well.
