Basic amp for KEF iQ5

This is my first post at Audiogon. I've just purchased new speakers - the KEF iQ5 and am looking for a basic amp (~$150). I've browsed a few forums and came across the following: Pioneer Elite A-35R, Sherwood RX-4105, Harman Kardon HK 3380-Z and the Sonic Impact gen 2 T-amp. Which among these (or any other ~$150 amp) would be a good match with the iQ5? I prefer a slightly warm sound in general, as opposed to bright.
I've been running my KEF Q15.2 surrounds on an Adcom 100wpcx5 amp, and they sound great. You might look for a 2ch. Adcom, the older ones don't run too much money.

Good luck,
