hi there, i have the sony 2400es amp and the kef 2001.5 speakers, iam looking to upgrade my amp too one that i can get 3d , i have been looking at the pioneer lx53 and the onkyo ,my question is can i use the kef with any of the amps because i still think the speakers are great with music and movies or would these speakers not do justice to the amps any ideas cheers
