No offense, but this part of your post is something that others can and will misinterpret. Schiit even says on the Web site: "up to 6W into 32 Ohms". The 6W output capability doesn't mean the Lyr is always outputting 6W into 32 Ohms. Headphones will use only as much power as they need. According to Schiit, you can use headphones as low as 8 Ohms on it. Of course, that doesn't necessarily mean that all low-impedance headphones will necessarily sound good on the Lyr (or even be usable with the 10x gain), but low-impedance headphones can certainly be driven by it with no negative effects.
Also, volume is not power. Turning up the volume does not mean the amp is sending more power to the headphones, nor does it mean that just because you can turn up the volume really high the amp is "powerful". Tiny battery-powered amps are capable of extremely loud volumes too, does that mean they're powerful? (Answer: No.) Most headphones use mere milliwatts to achieve loud volumes, so a high volume setting really doesn't mean anything. (Especially when amps actually attenuate the signal for some headphones, as opposed to actually amplifying.) The "up to 6W" of the Lyr really only comes into play when using it to drive orthodynamic headphones which tend to be very inefficient. Most regular dynamic headphones won't use anything close to the 6W headroom of the Lyr.
The only way to "break" a set of regular dynamic headphones with the Lyr (low-impedance or not) is to take the headphones off your head and turn up the amp volume to max, using really, really loud music (dynamically-compressed material would help). That would definitely do it.
