What is a good 2 Channel Receiver for driving Klipsch RF-25's for around $100?

I have a pair of Klipsch RF-25's that i have been using with a vintage (early 80's) Sony receiver that has worked pretty well up to this point, but the right channel now plays mostly static. So I need a new receiver (new or used, i'm looking on ebay) with the primary characteristic of having as full and neutral of a range as possible, for around $100 market price. Any suggestions?

The cheapest that I found is Sony STR-DH100 for $135
