Amp for klipsch KG4


I've got a set of KG4's I bought new around 1990. They are in very good shape so I want to put them to use. I retired them quite a while ago and have decided to give them to my grandson. I'm looking for suggestions on an amp that is well matched and affordable. A receiver, or integrated would be fine but if I can find separates that would be best. Since he is only 12 and has active younger brother and sister, solid state is probably best suited for him. Any advice is greatly appreciated!

Thanks for the replies, I've got bid in on a vintage Luxman receiver. I'll hook him up with an old manual pioneer turntable and CD player. Hopefully he'll learn there are other sources/formats than mp3, etc....

Actually I don't think he even knows there is such a thing as a two channel system.

Thanks again!

Any of the older Luxman SS integrateds will do fine. I used to run a L-430 with mine back in the early 80's.

Or even any of the Luxman stereo receivers of the late 80's early 90's. The R-113, R-114, or R-115 would all sound great. All have a very strong tuner and preouts/main ins.

The flagship R-117 would also work but the KG4's really don't "need" 160w/ch of raw power.

If you want good "synergy" I would look at the older Nakamichi receivers. They mate extremely well with Klipsch. Just make sure it is a "stasis" design unit.
I've always heard great things about the older Harman Kardon receivers and Klipsch. The HK-430 in particular.
