I was also wondering which post inspired the rant, but I agree with jethro1964. I own and enjoy Harbeths, but I simply can’t understand why Mr. Shaw sidesteps the amplification thing. To say any well designed amp over 50 (or whatever) watts will give you great sound does not make sense to me. It’s a very well designed speaker, and it will easily allow someone to hear the flaws in a mediocre amp.
Probably because he knows something about Speakers and electronics ;-)
He wanted to design a robust speaker, not too hard to drive, that would sound good with any competently designed amplifier. And you can find competently designed amplifiers for pretty cheap.
Personally I’ve found it to be the case: Harbeth speakers seem especially "amplifier agnostic" - I’ve heard them with a range of amps, from tube to modest solid state to more expensive, and they always sounded good, with the same nice qualities. I’m a bit of a tube-amp-head and I find the Harbeths sound smooth and full no matter what they are powered with.
