    So I'm thinking of picking up the Bang and Olufsen H6's (the H8's were just, ungodly - I was floored) or Master & Dynamic MH40's (equally floored). I have this DAC which is a noticeable improvement over the onboard audio on my 5,1 2010 Mac Pro (though I've heard newer Macs are superb these days) AND has a 4 pole input so I can use inline microphones on OS X - it works really, really well.

    Anyways, whenever I reboot the Mac there's a pop that comes through to the headphones - would this damage the B&O's? Or any headphones? I did a quick Google search and couldn't find any info. There's a YouTube video by the channel name of 'lachlanlikesathing' - and he had a faulty amp send a huge pop which blew the drivers in his multi hundred dollar headphone, but of course I imagine that's not remotely close to what I'm hearing with the NRG DAC. No apparent damage has occurred to the $80 Apple IEMs I'm currently using with the NRG DAC, but any input would be greatly appreciated!

    No one? I have a pretty good idea that it would be safe, but no one here has any input?

    Honestly depends on how big the pop is - though to be honest if it's just the pop that comes from the DAC starting up I can't imagine it'd be a problem. The power going to the headphones is no higher than what the DAC is normally capable of outputting to them, it's just that you're getting it on and then off fairly suddenly.

    Thank you sir. Makes sense; the Apple IEMs haven't appeared to have gotten damaged by it etc, and if anything those tiny drivers would be the ones to show it first vs. bigger on ear or over hear phones.
