you don't understand how amplifying a planar magnetic headphone works and are making yourself sound like an idiot. 

post #15302 of 20001

might i ask what your source is feeding the receiver and what type of input you're using

post #15303 of 20001

and could you please explain to me what you mean by sounds worse? your stereo receiver has inaudible distortion going by the specifications

This is coming from the same guy who said a waterfall plot showed intermodulation distortion.  You don't have to be so confrontational!

I just had to blow some hairs off my HE-400's left driver, I had some rattling on it during low bass.  I didn't know it was susceptible to that kind of thing; the diaphragms aren't sticky like those infamous beyer ones.

http://youtu.be/j77VKw9Kx6U this is pretty good stuff.  raven 37 minutes in he shows distortion through waterfall plot.  yes he's showing a speaker but the concept is the same

He flat out says it's resonance.

...lool. i can think of hundreds of better ways to spend an hour than watching that vid. like listening to music & getting drunk =P 2min in I was already bored.

and what is resonance

Another type of temporal distortion is resonance. This one is critical. Let's call it time dilation because it stretches the signal out for a longer duration than in the recording, in other words, lengthening the decay, or ringing. Stored energy that is not dissipated as heat is reradiated as unwanted sound. Drivers with poor damping and cabinets that don't completely absorb or block the internal vibrations of the enclosure radiate delayed acoustic energy into the room. This is a major contributor to the perception of, “It doesn't sound live; it sounds like speakers.” It is measured by the cumulative spectral decay, CSD.

post #15311 of 20001

Yes, resonance.  A far cry from imd.

I'm listening to the Pink Floyd album dark side of the moon, and can't get enough of this album through the he-400's! I'm extremely impressed also with the micro details that my hd650's don't reveal. Totally impressive!
