The quarrel between " 70 years old audiophile" as i am with my stereo and so called younger multichannel upmixer users is LUDICROUS...
Looks like those over the age of 70 could care less about Dolby Atmos and are using every excuse in the book to justify their very expensive awesome sounding 2 channel.
+1, and the anger that anyone else can enjoy something that is different than stereo (note, I didn’t say better than stereo, not going there).
Be it stereo or multichannel users , the only factor that matter NOW is : do you have the BACCH filters or not ? Because the only question that matter for 2 channel users and multichannels users is : Is your TIMBRE perception good in your system and how about spatial localisation ?
Two channels or more , the only thing that will improve sound experience to the TOP is the Choueiri invention ....Then why quarrelling ?
Psycho-acoustic is not a fad or a marketing ploy it is pure science...
Then stop arguing in completely outdate debate about 2 channels or more...
I cannot paste the whole page here read why :

I will not need more than my headphone if i bought BACCH filters ... HUGELY BETTER LOCALIZATION IN SPACE FOR STEREO USERS
Those with multichannels will enjoy it more...BETTER TIMBRE EXPERIENCE FOR THEM WITH NO DEGRADATION ...
There is no quarrel , only ignorance as usual ... 😁😊
