"So, if I said I prefer an all JVC/Bose system to an VAC/Von Schweikert system, y'all would just chalk that up to personal preferences?" In some/most cases - yup. If I wore hearing appliances that still could not produce something where I can differentiate between the two (and 'specially if someone was giving me the JVC/Bose combo as opposed to my buying the other for that case) then that would be a personal (and valid) preference. At least that combo produced something I could still experience and potentially enjoy. It's not always a tin ear - it might be a plastic & semiconductor ear, etc. Or, it really could be a personal preference and y'all know there's just no accounting for taste - either yours or theirs.
