Quote: And I'm not sure where you are getting that info, but between coarse grained Cu and nanocrystalline Cu there is about an order of magnitude difference in the conductivity, not 2.   Just look at this paper about differences in conductivity due to twinning in nanocrystalline Cu...

You aren't really plastically deforming the Cu unless you bend the cable quite a bit. Therefore you aren't creating any dislocations.   Considering you are using drawn wire, there are already a massive amount of dislocations present, not to mention the low stacking fault energy of Cu, which...

Since you said that the laser detector can only detect a fixed amplitude, do you sweep through different amplitude values to get a sense of how much the sample material is oscillating?   So let's assume you see a change in amplitude over the 100 hours of testing. The real test to see if burn...

I was going to write a long drawn out response, but I think the following will do.   You say that plastic deformation is not significant in the burn in process. Agreed.   If that's the case, how could the speaker materials change to alter the sound production qualities?   You said...

Here are my opinions. I own Grado 225s (not i), Senn HD598, and have listened to the AKG K701 a lot. Here are some bands you listen to so you know my musical tastes: Exivious, Cloudkicker, Animals as Leaders, The Faceless, CAB, Sylosis, Rush, Billy Joel, Michael Jackson, and a little Dream...

Quote: Recabling won't help. Neither will burn in. Your ears will just get used to them.

Enjoy the new headphones. Don't pay attention to any "burn-in" myths. I listened to a friends brand new K701s and then again when he had over 500 hours on them. Absolutely no difference. It's just your ears adjusting to the sound. Properly amping the K701 does make an actual difference though.

Sylosis' new album, Edge of the Earth is fantastic.   Don't like it as much as Conclusion of an Age, but it's starting to grow on me, especially Empyreal.

If he thinks the bass from the Beats was "STRONG and CLEAN" then I doubt he'll like the SR60s. 

All Shall Perish released a song off their new album. I like the song, but the sq leaves something to be desired.

Quote: I agree with you somewhat. Maybe there is burn in within the first few hours. Maximum. I don't believe in 300+ hour burn in or even 10+ hours. It's just your ears getting acclimated to the sound.

What cable should I get to make the 1s and 0s transfer better. I think my optical cable might be taking some of the 1s and making them 0s, and my music quality is suffering
