Both Denon AVR-S710W and Onkyo TX-NR646 are very popular on the market. Since both models do support 4K Ultra HD with 60 Hz frame rate, HDCP 2.2, and also various online services, it is indeed tricky to choose one out of the two. Well, let us see the comparisons below carefully before making a decision!
If you have ever gotten the chance to try out both products, you may have noticed that you need to turn up the volume quite considerably higher with Denon AVR-S710W compared to with Onkyo TX-NR646 in order to be able to hear anything.
