Funnily enough, even the upper registers seem to have improved (which I know is impossible). π
Chartz, after every service or repair of any of my vintage I think the sound improve, well sometimes it does, but an optical cleaning should be sound neutral, and even so I think it sounds better when looking cleanπ
Enjoy your MCs
