Hi this is my first post on this forum! My question might sound silly but looking for pros opinion on this. In terms of absolute sound quality only, will there be a big difference if upgrading a 12 -13 year old av receiver? Lets consider if it’s going from Yamaha Rx-v1900 to Yamaha A6A ? Edit: Sorry i should have posted my system details earlier here it goes: Amp yamaha rx-v 1900 - 130w range receiver running 7.1 Av source : Nvidia shield tv pro Front: Paradigm monitor 11 V6 Center: Paradigm monitor cc290 v6 Surround: paradigm monitor mini v7 Front presence/height: paradigm monitor atom v7 Sub: paradigm dsp3400 Projector: Optoma UHD 38x Denon dvd player 1930 or 2930 which now hardly used. 60% music videos 40% movies mostly on youtube and netflix Getting that urge to upgrade my system considering av receiver for now or it should be the front speakers? Though speakers still sound great just like when bought new !
