Yup. Most DC coupled amp makers use a DC servo circuit that basically nulls out and DC componant (and AC up to maybe 5 Hz.

Also, good headphone amps have a high damping factor that causes the driver to move only with the music and not rattle around under it's own inertia.

Assuming you are listening at less than ear bleed levels (and you shouldn't listen at any where near those levels) the premis of this whole thread is just wrong. If you do listen at very high levels you are LESS likely to damage your cans with a good amp as it is doing a better job of keeping the drivers under control.

So long as neither are pushed into clipping (becasue that can heat up the coil), and neither are pushing the driver beyond its physical limits. Garrett

Sorry, I just don't understand your point here, I don't see any issues with Hirsch's statement as written.

No point really... Im just adding to it. I agree with hirsh's statement and am not trying to correct it.

I thought the same!

Thats why I connect my Disney Donald 70 Anniversary Radio to my full-size loudspeakers without amp.

I'm not getting much of sound but my loudspeakers sure will last!

Now seriously, nothing wrong with ask, but your concerns have no justification. Just get an Amp for more Ohmp!

OK, I understand you now, I reread Hirsch's post very closely four times and couldn't find a flaw, I was wondering what I was missing!

so according to tyll.. a low gain setting with the volume knob set higher provides more current and therefor better driver control.. resulting in safer conditions for your headphones?

i may be completely wrong... we havent gotten into electricity or sound in physics yet this year, although i cant wait... ^.^
