He seems like a nice dude, but a credible audio reviewer? Nah... IMHO, this statement is absolutely disqualifying.
"After 150 hours the sound got worse. Flatter, as if the bass dropped off. I ran them in music room #2 for weeks and then when I brought them back to my main system they sounded totally different again. After 400 hours they are simply incredible, some of the best speakers I have ever heard."
So the speaker changed from "worse" to "simply incredible" between hours 151-399? Sheesh....
Break-in, beyond a few minutes to hours, is a myth. ..Read the Q&A on the website of Bob Crites, notable Klipsch expert and designer/mfg of replacement crossovers and drivers. He emphatically debunks the break-in myth.
Also, how can he possibly claim it's one of the top 20 speakers in the world until he has heard every speaker in the world? ..Not to mention hearing them in the same environment. ..To say it's the best he has heard, fine... But claiming it's the best everyone else has heard is kinda ridiculous.
I get it. He likes his new speakers. ..But reread his review of the CW3. ..He made many of the same glowing, exaggerated, and unsubstantiated claims about them.
