Would love to hear your opinion!
I also have been into audio since building my own amp and speakers back in the '60s to having a dedicated listening room for the last 25 years or so.I am a long-term audio fanatic, with a high end 16 channel Dolby Atmos system at home.
I find that the latest multichannel formats to be worlds ahead of the surround sound of 30 years ago. Dolby Atmos, DTX, and Auto 3D are well executed, and come alive with a capable processor.I also have been into audio since building my own amp and speakers back in the '60s to having a dedicated listening room for the last 25 years or so.
I almost never watch films though and most of my 7000 ish discs are mono or stereo so I haven't invested much in surround sound, just centre, rear and sub for films.
Years ago I spent a lot of money on car audio but eventually came to the conclusion that because the relative positions of listener and different frequency range drivers imposed on us by the car environment is too big a compromise to be compensated to give good enough sound in a car for me to enjoy - so gave up.
Much more recently I suppose DSP can resolve some of the problems.
Nowadays I only listen seriously at home, usually drive in silence, and have the standard audio, which is acceptably low colouration and has an unexpectedly even frequency response (with tone controls flat) but the usual problems of imaging due to listener/speaker positions.
Reading about car audio most non-audiophiles like loud with hugely boosted bass and treble it would seem. Can be nice on pop music but dire on speech and acoustic IME.
