Most forgiving high end speaker 10k-20k?

I think relatively "frequency flat" speakers are the way to go, and among most good speakers one should appreciate accurate treble as an important part of the musical experience (tonal "cues"), and only bothersome if your system has something wrong with it. If you try to use a speaker as a harshness filter everything cool suffers. Try tubes (love 'em)...or let your ear hair grow out...but keep the crisp! Everything from rustling leaves to a mandolin needs it. Don't put gauze over your earglasses to mute the tawdry aural wrinkles or you'll miss all of grandma's character.

First time I heard the Beatle's "I'm Looking Through You" I was stunned by how amazing it was...on a 4" (maybe) single crappy dashboard ('61 Dodge Lancer) car speaker. I've listened to Yamaha NS10s in major recording studios and still think being waterboarded would be preferable to ever hearing those damn things again. I think ancillary gear, the music, and your taste is all that is ever happening, and to sort of paraphrase an old Buddy Rich comment, "there is no bad sound, just bad music." This isn't true, but it certainly made me feel better to write it.
