[New home theater receiver]

Be sure to verify watts per channel in light of your speaker Power requirements requirements - at least 80% of your hungriest speaker’s RMS; if it can do Atmos without external amp etc.  I purchased from that company and had to return the receiver and they have a 20% restocking fee AND you reimburse their original shipping and pay for return shipping.  Yes it was a costly mistake!

Lol I’m the 2019 newbie and those same speakers gave me the same impression. My receiver WAS underpowered and I have exchanged it for a receiver that can drive all my speakers. If you are still using this forum I would like to know how things eventually worked out
