OK, I've considered the crossfeed controls only with regard to simulating near field monitors and therefore did not bring them in connection with headphone specific tuning possibilities... which might to some degree be possible, but they should only affect the room feeling, not the tonality. But I'll have to wait for my unit to test that.
Laphroaig is a good one indeed... long time favourite of mine. Pairs well with most headphones.
Pairs well with hot tubs also :)
