I play classical guitar. I find HD650 + QuickStep deliver good tone color of classical guitar music too.
The music files I listen to are in AIFF format.
One thing I may not be very satisfied at this moment is that this combo is a little bit shy of energy when playing big symphonies. Perhaps it is due to the fact that both QuickStep and HD650 are not fully run-in.
Now I am thinking to get a 15V power supply to juice up my QuickStep.
