Dear Johnk, very interesing question(s). Since this early morning, I'am busy with putting my reflections into words. Here's the result🤗
BDW, I am working in a project where music is used to light up areas of catatonic people’s brains. It is a way to activate these people, getting into a kind of conversation. And it works! Using a specific music title as an anchor. They show a reaction when hearing a tune which is memorized in their brain and than we try to get a conversation started.
Binaural hearing is hearing with two ears. Since ever, this helps human beings to orientate in the physical environment and eventually recognize potential danger. So, our hearing is kind of a 'survival gear'. To be able to listening to music in 'stereo' is added value, imo. But, isn't stereo reproduction artificial? It is not possible to have the exact sound field that actually existed during the recording or the live concert in your home (or anywhere else than the original location of recording).
Coincidence? Yesterday I have readjusted (not the first time..) the place and direction of my 2 speakers because some night critters 👹👿 must have been moving them (again..). Some 30 minutes later, I was delighted with the sound quality when sitting in the sweet spot, listening (not only hearing) to music. To me, for example some tracks from Buddha Bar are sounding really nice in stereo under 'good' stereo listening conditions (including sweet spot). But then, it's electronic music, artificial. A play with sounds. And with an artificial sound stage.
During the past years I have figured out, that I like stereo listening most the less instruments are in play (vocal and 2 to 4 instruments). What I do reckon - it's mainly the 'quallity' of the recording and mastering which brings the listener as close as possible (which imo is still far away) to the sound field that has been produced by the environment when recording. For example, listen to Norah Jone's 'Little Room'. Or David Klein Quartett 'My Marylin. And 'Chanchullo' from Ruben Gonzáles. Then you might know what I mean. Listening to these records, not sitting in the sweet spot is not the same pleasure to me. In this case, 👍for me to stereo and seated-centered solo listening.
I own some records from the fifties which are incredible to listen to, with a very good sound stage (I use a mono cartridge with a mono preamp, including a shorting plug for one input channel to get 'real mono'). Basically, I should use as well only one loudspeaker to have realreal mono.
I have figured out that listening to mono recordings can be less tiring than listening to low quality stereo recordings (some jazz recordings from the beginning era of stereo recording). But for good stereo recordings, there should be no listening fatique per se. Basically, if in good health, I believe our brain is very well capable of processing that many information in question.
Basically, I agree with your comments. I guess we need to live with some compromises when listening to music at home.
Cheers!
