Well yes 110 dB is okay. I do like loud though. When I hand my headphones to anyone else they always turn them down because they say it is almost enough to hurt their ears. Where for me the volume is just getting good. And if my Mac is 45mW (I mistakenly remembered 50 before) with 1.2V that makes the current 37mA. All of those numbers are just a hair below the “Fairly loud” figures on the digizoid calculator. And that is exactly what I expected from experience before looking at a single number. When I set the volume to 90% it is what I would call “fairly loud” (but not quite loud enough), but when I kick it to 100% volume it begins to distort a little. But that leaves ZERO room for EQing. I would have the draw the preamp down to make it much quieter to allow for a +3dB increase anywhere, if I want to avoid distortion/clipping. The signature is pleasant at that point once I draw down -6dB out of the problem 500K, but then the headphones are too quite.But, assuming for a moment that your source is not current-limited, 50 mW into a 93 dB/mW headphone would yield about 110 dB.
Is that not enough volume?
The simple fact is that I have the wrong headphones, but rather than chase 30 different headphones, I figure I will stick with the girl I brought to the dance rather than searching the room for a new one. She’s just Janie Briggs with the glasses, ponytail and paint covered overalls (Not Another Teen Movie reference). A bit of EQing and the signature is just as happy to my ears as my D40x’s (with way better clarity).
By my calculations *pushes glasses up bridge of nose* I will get to get away with around a +3dB increase or a bit more from the NX4 versus my Mac. This is assuming the doubling power requirement of a +3dB increase is purely current. The Mac caps around 37mA where the NX4 at around the same voltage is 66mA. Maybe I’m wrong (you guys know infinitely more than me about this stuff) but that should allow +3dB safely.
On the other hand, the Atom which is also coming in the same day will allow around 1A of current which will be more than enough to EQ that headphone to death if I wanted to. Though +3dB should be fine, I might want a bit more and the NX4 likely won’t allow that. So we will see on Tuesday.
