    Thanks, Apple.

    I listen to the headphone jack out with some very sensitive IEMs (inner-ear monitors)... anything above 1 click on the Mac's volume and it is too loud. Half volume on these would probably be deafening... so I stick to 1 click up.

    On my old 2008, there was a horrendous noise floor at that volume level. On the 2011 there is still a bit of hiss and hum but it is much, much reduced.

    You do know that if you hold the Shift and Option keys while adjusting volume, it moves in smaller increments, right?

    Still way too much noise for my Triple.Fi 10 IEM's with the new 2011 13" MBP. I just use a FiiO E7 USB DAC/HP Amp; no noise whatsoever.

    I'm not sure how they eliminated hp jack noise after the first gen iPhone yet it still exists in their multi-thousand dollar laptops that are aimed at music professionals. Oh, well.

    You're right, it is still too much. I guess I was just thankful that it is much less than the 2008, which was almost unlistenable. I have Westones and an external headphone amp but I've never invested in a USB DAC.

    Whoa I didn't know this. Don't have my mac on me at the moment, but you hold shift + option + vol up/down?

    Nice to know, the HP desktop Ive been allocated at work sounds like the inside of an ICU with no music playing. :mad:

    Yep. It makes about 5 steps for every one without the keys.

    It doesn't work on the 10.7 developer's beta, though.... I need to restore back to 10.6... There are just too many bugs with 10.7

    When you're on a beta OS, all bets are off! My beta testing days are behind me. Now I'd rather let others be guinea pigs!

    you could also look online for an attenuator to get separately like the one that comes with these:

    DAC's are great! It's one of the benefits of having recording gear. I almost never listen to any mac's built in audio. I use a firewire interface with my monitors. :D
