Well I have one anyway so I guess I'll find out when the headphones arrive in the next couple of days. I've read that they scale well, but yes, it is the Conductor's power that concerns me. I'm hoping the low gain setting will give me room for manoeuvre with the volume pot.
Burson's tend to be decent pairings with low impedance / high sensitivity headphones. While I've never heard the Conductor, the Soloist played well with my D7000.
