Hey so awhile back i bought the ibasso d10 amp with a pair of DT990-600Ohm headphones, sadly i realized fast that unless i plugged my headphones into my huge yamaha home receiver i didnt get much out of them.  i love the sound of my headphones and i was considering jumping down to the 250 ohm pair of the DT990 line.  is there going to be a massive sound difference?  if so is there a pair of more bass heavy headphones that would pair well with my current amplifier?  BTW i prefer open to closed cans, gotta keep a ear open for assassins and ninjas right?

Or is there a great sounding pair of ultrasone headphones cause ive heard they make great semi portable cans.
