I'm 72 and have some high-frequency hearing loss. Bought a new SUHD Samsung TV and would like to improve dialogue as well have a nice music system (no hard rock). I am definitely not an audiophile (it's like a foreign language). Thinking about Quintet set of speakers (like the size) and using an old Mirage BPS100 sub that I already have to make up a 5.1 system. Might want to add Atmos speakers at a later date. Maybe a Yamaha RX-V581 avr that will also permit an outdoor patio zone. Will this be an improvement over 70s era Yamaha CR-840 avr and 2.1 Edge wall/Mirage sub that I am now using ? Room is about 13 x 15 and partially open on both ends.
