"Every 303 I've owned or restored (30+ of them) has exhibited a barely perceptible 'ringing' on the upper midrange into the treble on some material - it's only really there at higher volume levels and on modern (digital) recordings on modern speakers (my vintage hybrid ESLs don't show it up but my Celestion A3s do), adjusting bias slightly upwards helps but nothing I've ever done has resolved it completely; I concluded it's just a side effect of a circuit design from the days when component technology was far less perfect than it is today."
