wow. sorry to hear that. thankfully it was not worse!
when bad falls on my lap I get completely focused on that one thing, and not how grateful I am for things not having been worse.
Musical enjoyment comes not from listening to it in stereo. it comes from listening to it.
live events are not neceessarily in stereo.
stereo did not even come along until the late 50s or early 60s.
all is not lost.
sinus issues occasionally affect me enormously. at times reducing me to almost one good ear, by lowering my sensitivity tremendously in my left ear. When unaffected the left side is down from 2db to 5db with regard to sensitivity, so I can at least partially relate here.even with one ear I can detect the sweeping changes in a stereo reproduction. tonal changes. And discern specific instruments.
the experience is impacted but the true involvement remains unaffected.
IOW... I should think fav genres and fav tunes are still favorites. listening posture too is gonna change a bit.
from an 'unattached' view point, I'd say there is sure gonna be a bit of adjustment now. as such, I'd do my best to let honesty and compromise lead the way. I'd say too as being an audio nut was not altered, outright system wide downsizing is off the table.
maybe replacing speakers is in order, I'd offer if for no other reason, there will or could be at the very least, an esthetic upgrade if the current standards are exchanged.
esthetics are quite important for the unafflicted audio nuts. sometimes they are the solitary reason for acquiring them. go figure.
the first post herein says it all I think.
grab the wife, and go see what things sound like at a dealership or two, bnearby and then decide, for your wife and yourself. together!
I'd offer too , its her turn to choose, that is if it had been yours in the past.
I've heard too when one door closes, another one opens.
it took losing my sight for me to begin looking for the next open door rather than to bemuse and ruminate over that loss.
life did not stop abruptly as I thought it had, it simply took an unexpected turn. drawing on my former military service, one adage prevails in life, 'Learn, adapt, overcome'.
very good luck going forward to you and your's.
