I have yet to explore the market.
Auditioned a purpose built Focal Chorus 700 series 7.1 setup. Front's were 726.
Then Kef 5.1, Marantz amplifier, Adcom amplifier, Yamaha (viewed only), Denon amplifiers (X500,X1000,X2000), Klipsch Ref series, Definitive Technologies and few more 
There is much more to explore. It will take time but yeah its a whole new experience. But I will still say, Car Audio is car audio
