Here's a couple of suggestions. I also like Onkyo and would recommend it to a non-audiophile looking for a good receiver.
Also, since prologic receivers are in low to no demand, he could pick up a nice used one for little $$. My experience with several Yamaha and Onkyo prologic receivers, which can be used in 2 channel, has been very positive. I still keep a couple of them for spares. And, they are solid performers.
If he could find a pre-Superscope Marantz stereo receiver in good condition, they are excellent 2 channel receivers.
