The voice issue is not solved by using a receiver in most cases. That discussion has way more priors than I can tell you but most often you set the audio track to stereo and voices for many titles come back.

This is upsetting to folk that want all the 5.1 glory but miss that all that drowns out voices.

Anyhow, if I were to shop today I'd hit AVS Forum and see if I can stay in the top ten best sellers at https://www.amazon.com/gp/bestsellers/electronics/3213035011/ref=pd_zg_hrsr_e_1_3_last
That list and work down the list to one with more than one zone.
