To clarify, Alan Shaw believes(probably in an act of pretense) that all amplifiers sound the same and differences are non-existent between well designed amplifiers. He has explicitly mentioned in the user forum that a double blind test(unsighted) will reveal differences between amplifiers to diminish to nothing. That is the reason why he always advocates inexpensive amps with the Harbeth as in his mind most high-end equipment are considered as a rip-off, which can be true in some cases.
I'm not too sure if Herman's first post in this thread is a tongue in cheek. Most higher-end equipment sound better than the mid-range stuff but that does not necessarily guarantee that they are indeed "better" in most cases. It all depends on setup, system matching, listening preferences and some other factors. There are so many variables involved that it is quite impossible to assess or evaluate the quality or performance of one particular gear without taking all other aspects into consideration.
I guess Tvad hits the nail on the head with his analysis. Alan Shaw thinks about his speakers first and foremost as associated equipment take a back seat.
