Dude, get it fixed, they look like fucking dolphins going "oooo". Sorry, hate to be blunt, but I'd be a lot more pissed than you're being.
On the other hand, when you're diving, they'll be right-side up.
Oh wait, you won't be wearing them then, never mind.
You can do it, but at 1/20, it's not worth the effort. 590V is close enough to 620V that you'd probably have to A/B the two to be able to hear the difference, but wouldn't be able to hear it on its own. "Probably".
So you're redesigning a digital interface? Like Coax or XLR?
Sorry for the mundane question, I guess I'm just trying to point out that you're really NOT trying to redesign a digital interface, you just want to amplify it enough to get from point A to point B.
I don't know if that helps, though.
I don't have a center channel and it sounds just fine -- see "phantom center channel" (any pre/pro or receiver can do this -- you just "tell" it that you don't have a center channel, and it should automatically mix the center channel to the front left and right).

Really? You're going to be just like those uneducated high school boys that I saw a special on so many years ago, you're just going to raise your hands and say, "not my problem"? Really?
At least get a vasectomy, you irresponsible, self-centered, hedonistic coward.
The only thing Dusty like more than black is black mother of pearl (or, "off-black of the psychedelic variety", as I like to call it).
Damn, that's $200 I didn't want to spend. I really need to get on the ball and sell some stuff.
Maybe it's because there isn't anything positive to say about it. Do the triple-fi 10's really need amplification? (I.E. in the same way the JH13 doesn't really need additional amplification?) I would point him in that direction. I have been happy with both Etymotic ER-6i and Yuin ...I forget, PK-1, PK-2? ...without additional amplification.
On the contrary, even though I'm (relatively) silent (on the subject), I remain interested -- thanks for the update! No rush, school comes first and all that.
