Need power amp suggestions for ProAc Response 4


As far as I know ProAc Response 4 is not easy to drive. Any power amp suggestions will be appreciated. Thanks.

My budget will be around 10K for a used one. I prefer a solid-state power amp, since I have a ARC Ref II preamp already. Thanks.
I understand that Edge gives a discount to customers without local dealers.The Edge NL-10 monos {225w/ch} at 13k {list} or try contacting Bruce Jacobs {Sound World:920-733-8539}.My friend bought a set and couldn't be happier.
