Yes, as others have mentioned it. I am not sure why you are complicating things. Why not listen to it directly? Most low impedance headphones don't have the impedance vary with frequency. The only exceptions I know are Sennheiser 5XX and Koss KSC75 whose impedance do vary. For high impedance (>300ohm) cans, it is less than 300/8 and it shouldn't affect the FR.
I would say just listen to it directly and enjoy the music.
Edit: $295 for the Apogee Groove? My dropped jaws haven't recovered yet.
