It took me 10 years to find the right speakers. Finally got Harbeth 30.2 40th anniversary - My room is not big enough for the 40.2.
Awesome, was worth the wait. Harbeths are unassuming at first but as others mentioned, you get to appreciate it more and more over time. So natural and clear. Very versatile, except may be for hard rock.
My Pass Lab x25 is a match made for heaven for this speaker and I also agree that an amp with some power depth, like this class A will bring the Harbeths to life as their db sensitivity level are low compared to other speakers.
Let us know how they sound in your room. Good luck!
