weakest things of harbeths are these.Far away from natural
drum set, cymbal shimmer, bowed bass
I respectfully disagree. Just got done listening to Zuill Bailey's most recent attempt at the Bach cello suites (Octave Records OCT-0008), and while not a bowed bass, the sounds I heard expressed the humanity of both the performer and the composer with spine-tingling authenticity. Earlier today I had on Basie "Live at the Sands" (their performance in 1966 before Sinatra took the stage – MFSL 2-401). When Sonny Payne cracked his drums I just about leapt out of my seat. I had to play it again to believe it. I was there (who needs Frank anyway when the Count's in town)! That on a humble set of PSesr speakers (with a little help from an REL T/5).
Now I'm sitting in a smallish, well damped room (13' x 21') about 9' from the speakers listening at about 80dB (pretty loud for me, but my wife wasn't home). The speakers behaved admirably (as usual).
Note that these speakers require some juice to get going (I've got 2x 110W with 120,000µF caps). Not really huge, but more than you would expect you would need for such small speakers, and enough for my needs. My old 60w amp didn't have the punch to drive them.
PS: Frank would always request Sonny Payne whenever he played with Basie (yeah, he's that good)!
