Yes. Someone once pointed out the quacking sound that polyester caps make to me and I've hated them ever since. And I agree that a good servo-controlled amp beats capacitor coupling hands down every day of the week. Case in point is the venerable Crown 300.Some people are sensitive to hearing phenomena than others. Once these are pointed out to others these can be detected. Sibilants were a case in point with me and I learned that about 30 years when a friend listened to a couple of amplifiers that I had built auditioned on his speakers at his home. He mimicked a sibilant sound by mouth and I have hated overemphasized sibilants whether due to amplifiers, loudspeakers or source material ever since. At the bass end of the audio spectrum this has to keep time with the music and drums should start with a bap rather than boom. This is probably more due to speaker design as amplifiers should have good damping factors if the power supply is engineered properly. I have built capacitor coupled output amplifiers and direct coupled ones. My preference is for direct coupling. The only capacitor coupled amplifier I built was the JLH 1969 Class A amplifier which is still popular - in my view the 1996 direct coupled output update is a better job.
