A string sounds wrong

Last week I changed the strings on my Yamaha acoustic, gave frets and fretboard a light cleaning with steel wool, put on same gauge strings, except the new were D'addario Phosphor Bronze, the old were D'addario XL Life. Now the A string has this strange tone even though by ear or electronic tuner it is in tune. Hard to describe, not a buzz, apparent when played open or fretted, it just sounds more “strident” or ???

I sighted down the neck the action seems fine, no changes have been made to setup since purchase 4-5 years ago. I've changed the strings many times, never had this happen. Even removed the A string and replaced it with a spare I had, same result. Only thing I can think of is the new strings were about a year old, but they had been kept in factory sealed bags under normal conditions. Any ideas before I take it to the shop?

Probably down to the difference between coated and non-coated strings.

I started with nothing - and I've still got most of it left.

Would that not be noticed on all strings? It's just the "A"

Is it seated right in the nut and the bridge? Issues there can cause weird overtone sounds.

If you play fretted notes up the neck is there a point at which the wrongness of the sound goes away? If so there's a fret issue.

I had a problem with my B string and found out that the angle of the slot in the nut was flat, not angled like it should of been. A touch up with a nut file cured this problem for me.
