It's not so much that it doesn't matter, as the engineering is much more important than the resultant efficiency. I would answer your other questions, but the first page I ran across when I googled SET vs. push-pull didn't jive with my understanding, so I'm just going to shut up. Try audiokarma.org, sh.tv or one of them other audio forums.

Sony MDR-V6/-7506 -- a little bright, but nice bass. ~<US$100 Also meets most all of your other criteria -- not sure how your head is shaped -- specifically, your ears -- but this is circumaural on about 50% of the human race. See if you can find a pair to try on, for instance at a local Guitar Center. Relatively light. Can be made extra comfortable with the "Beyer pad mod".

Agreed.

I'm using Quad 12L actives -- I intend to eventually get a subwoofer to fill out the bottom octave or so.

If you blur your eyes, it almost looks like a bunch of ASCII text in a scrollable code window.

Actually, I have used a Sony MDR-V6/-7506 straight out of a laptop's soundcard -- it sounded a little bright and rough around the edges, but not that much different than it would out of an amp. (I.E. I don't think it scales much at all -- the roughness would go away with a different source, but that's about it.) Also, I've used a pair of Etymotic ER-6i's directly out of a Creative Labs Nomad Jukebox 3, and it sounded surprisingly good for portable audio -- I've stated before that if you're not going to use an amp, then that's the way to go for entry level IEM's and portable audio. So I guess I was arguing with the general statement, since that's the direction you took this debate, and not specifically with the Denons, whose scaling I have little experience with.

Do you really think that having a HD600 or HD650 scaling well is a good thing if all you had was a cheap MP3 player with a miserable headphone out -- no amp, nothing else? If you do, fine, but I disagree -- I think there's a threshold below which you may not want to go. I do not think that having an "upper-mid-fi" rig would be bad with Senns -- I recently recommended exactly that with an AudioValve RKV here recently, but I specified the circumstances that I thought it would not work well, both in this post and in the post when I initially made the statement.

That's why I added the qualifier "necessarily". Meh, I guess -- mine needs new pads, and I bent/broke the 1/8" pin. I guess I like it enough to keep it so far. Do you still have yours?

Fascist. Pfff. And: meh.

Can we make this: ...into a smiley, please? , perhaps?

Yup.

It's not what you stated, it's what you assumed/implied -- that the HD650 is just better, and whether or not I agree with you is a function of upstream equipment. I disagree, let's leave it at that. (Just so that what I am assuming/implying is clear -- I think it's just a matter of taste. I value a straightforward delivery more than anything, and to me, the Senns are just too laid back in the same way that Grados are too forward. To me. ) Oh, and "scaling" isn't necessarily a good thing -- if you can't afford the high-level upstream equipment, then what you're saying is, you're hearing an inferior phone (to itself even).

I would hardly call Hirsch's rig "mid-fi".

Clean your office. That always surprised my admins.

Actually, I like it better than the 650.

No, they don't -- that's what we're going to be stuck with because of the writer's strike.

Man gets offended by http://www.youtube.com/watch?v=YMaiXSiYVck . Gee, maybe he shouldn't have done whatever he did. I hate people who "justify" their issues like this. What's the word for this, "externalization"?

So...good, since this would be the first step? You'd have nothing but reality TV on all channels at all times? Or do you just mean "Hollywood", and not "the movie-making industry"? 'cause I kind of like movies. Some of them, anyway.

Apparently, Black is Green.

That was worth clicking on. So what happens when I post it as a link? EDIT: okay, now with the noembed tags [noembed] [/noembed] Okay, cool, that works exactly as I'd like it to.

Too fucking hip. Thanks, Todd. And for those of you who are on low-bandwidth type situations, I highly recommend the flashblock add-in for Firefox.

Yup; dewing et. Already got the quote, just waiting for funds. They will also have the A900ti in December timeframe, although I'll probably get them from audiocubes, even though it'll be just a little bit more expensive. Maybe. Perhaps.
