I would do that deal with your buddy. Good speakers are good speakers no matter what they’re playing. Games and movies have music and all kinds of cool sounds, and the speakers don’t care. They just do the job. IMO, Ht or music and games benefit from better speakers. Some people’s opinion is that with ht you can just use whatever. But to me that’s ridiculous.
The AVR is definitely entry level, but should work nicely for a long time, until you feel like it’s time for an upgrade.
