Would this be of any assistance to me pushing to either: Grado SR-60i, Philips SHP9500, or Skullcandy Aviators? My source would be either my laptop's Creative Sound Blaster Recon 3Di sound card or my Fiio x1. I just don't know what I'd gain in use of an amp for the cans above.
deftranceFor those headphones, no you don't need any amps. But hey, you can always get one and get a pair of headphones that will need an amp next time. :)
