agree w you completely
there is no unanimity - harbeths as high end speakers go, are pretty easy to drive, reasonably efficient -- and thus many many many amps work just fine, just depends on the priorities of the owner... better amps sound better for sure, the speakers, while warm and full in tone (p3’s less so than the bigger brothers/sisters), are sufficiently transparent to be true to the quality of source and the amplification
i personally feel the compact 7 and up like very high quality ss amplification more than tubes -- brings a bit more snap to the speakers and make the full bass more tuneful and tighter at the margin
yes alan shaw plays this game about being totally amp-agnostic - smart business decision, is all i can say... momma didn't raise no foo...
