  Hmmmmmmmmmmmm.  Windows here so cannot comment on possible settings to pursue on the Mac.  Do you have another source other than the Mac to try things with?  Another computer, a Blu ray player with optical into the Bifrost optical, or even an Ipod ran into the Lyr would start to narrow down what is going on.  Only other thing off the top of my head is does your player have a volume control like itunes or does it lock that out as well?

thanks for your help! So i tried my windows laptop, still through USB (dont have optical on me anyway) and here I'm able to adjust all my volume levels. I ensure my system volume as well as my tidal volume were set at 100%, but stil i was able to take the volume knob to past 75%, reaching 100% momentarily before it got too loud. Problem too is at those levels graininess and or noise is also introduced.. Ugh.. not a pleasant experience. :/

I would consider contacting Schiit about it, email don't try calling.  Explain you have tried it on multiple computers and it does it on both and that you are on high gain.  Do expect a fairly short answer as they are usually short and to the point with responses.  
 
Only thing I can think of to start doing is process of elimination with equipment and make sure it is the Lyr and maybe not the headphones would be to try another pair of headphones doesn't really matter what ones and see what volume you can get out of it.  Also, could the tubes be bad if you have another set to try.  For reference for me on low gain here is where I usually run it for high volume (not ear bleeding point but comfortably loud).
 
HD 800's - 300 Ohms - 11 to 12 o'clock
B&W P7's - 22 Ohms - 8 to 9 o'clock
vModa m100's - 32 Ohms - 8 to 10 o'clock

As many others have noted elsewhere, if there is a problem Schiit will promptly resolve it. I had a defective original Lyr (crackling in one channel, even when tubes were switched) and they sent me a replacement.

My volume knob is usually between 10 and 1 for most of my headphones that I use the Lyr2 with, gain is on high, windows volume control is at 75 out of 100, using optical to UD-301 or Bifrost Uber.
Headphones used on Lyr2: HE-400/400i/560, LCD-2f, TH-600, K7XX

is this along the lines of what you'd expect? the k7XX is around 60ohms.  also when listening to classical music, do you push the knob any higher?

I use the K7XX mostly for classic rock and new age, also I've found that my Project Ember drives them better than the Lyr2.
 
For classical its always my HD800 with a BH Crack, hard to beat this combination IMO.

Hi guys, I think I'll be a new Lyr 2 owner soon in addition to a couple of new headphones as well to go with it. Just a few questions I have about the amp.

What gain setting should I use for these headphones? HD650, HE-400S, and Q701

And should I get the LISST in addition to the stock tubes? Should I buy any other tubes while I'm at it?

I don't like the LISST tubes as much as the tubes that came with it. I guess I just like the tube sound more. For me I use low gain on my hd650. High gain seems to be giving me some hiss and other sounds.

Great to hear that the tubes that come with the Lyr2 are good! I wondered, since there are threads that talk about tube rolling (swapping, but I guess here we call it rolling, like log rolling).  I certainly love mine with its stock tubes!  Even bought a second pair of the same tubes, just in case.

I literally got my lyr2 3 days ago so I don't know much at all. Just that to ME the stock tubes sounds better! I'm looking into amperex 6dj8 orange globe to try

@kayandjohn, @magnum703, if you are going to roll a lot of tubes suggest getting socket savers and some Deoxit.

[magnum703]

@DavidA, I read that those cheaper priced ebay socket savers are pretty much the same?

My Lyr 2 came in today...just a few more miles away from home and then I can fiddle with it!
