Skimble, there is no telling what setting the two receivers may have been on at Best Buy. And, if different speakers were hooked up you were probably hearing the differences in their sound and not the receiver. There are a lot of possibilities as to why you heard things the way you did.

If the Pioneer does everything you want it to and sounds good to your ears, stick with it.
