It does not have the slight tendency to have a sharp edge or sibilance in the upper midrange that the Harbeth has, but, it sounded a bit drier than the Harbeth, so tradeoffs are involved.
I only just resolved a sibilance issue that plagued my system for well over a year so I’m particularly wary of introducing anything new into the system that might reawaken that particular sonic demon.
At the same time, "dry" is not an adjective that I tend to regard positively. Perhaps Spendor is a better direction for me to pursue than Harbeth or Graham. RE: amplification, I have no plans to replace my Hegel H390.
Are all Audio Note speakers designed for low wattage tube amps? ? ?
