I read a LOT of reviews and user comments about Harbeth & Spendor before picking up a gently used pair of 30.1s. Everything good anyone said about the 30.1s is true. I can pick nits (the mid- and low-bass aren't as thunderous as some other 8" woofer designs), but that matters less than the overall "voice" of this speaker--they sing music to me.
I couldn’t possibly fit a 40.1 or 40.2 here, but I heard the latter once and was really wowed. Easy to hear, even in a poorly damped show room, how good that one sounds.
