Most likely excessive gain for low impedance cans, however always a possibility it's oscillation (especially if using a socketed opamp).

You can toe them in up to ~15 degrees. Otherwise you'll never hear them on axis.

Soylent Green. A fav classic. New Sci-Fi can't hold up. I won't spoil the ending...

Christmas Gifts, but telling you would spoil the surprise!

Boxed mac & cheese (~barf), a salad, and soon yogurt with some kind of fruit or honey.

whatever has been left on the set...

Build your own! A small plastic box, a couple resistors, input terminals and a headphone jack. Definitely doable for less than $10 (if you already own a soldering iron). Here's a page to get you started... ---> Headphone Adaptor for Power Amplifiers Lots more schematics floating around...

For attenuation, a 10k pot is a good standard for most situations. A little better all-around compromise (nicer to the DAC) would be 20 or 25K, but then you really have to make sure you use good short cables (3' to no ill effect). 50K would push it for any passive. With a 25k pot as a passive...

never credit, gotta save up and buy qwerty or devorak?

Just stood 10' behind someone today waiting for a bus. He had ipod-ish earbuds, and could CLEARLY hear the music he was playing. That's too loud.

You don't need distortion to blow the driver. Even a clean signal with enough power can fry a driver. Can also happen through time with fatigue. Or you can induce distortion by hyper extending the diaphragm, making it's alignment go wonky. This can also happen if you blow heavily on the driver...

Deus Ex was a fantastic game. Now playing Reversi and Mahjong.

Wow, good deal for a first meter. Nothing to regret. After a while when you know you'll be getting into more serious electronics, you can then easily upgrade to something lots fancier, like a Fluke.

If in Canada, Canuck audio mart...
