RE: A way to identify if sibilance is in the recording or your system

For some reason I can't get the recording. The links in the OP seem to be to Pizza Hut. It does not give me "Open in new tab", oh well. But I know the subject.

One piece that I think would show sibilance it Ten CC - Not In Love. If you want to hear it not in the voice you should be able to hear it in the cymbals in Humble Pie - Hot N Nasty. That thing was a train wreck to record on to cassette. Without Dolby HX forget it. Was just a song you didn't listen to in the car. (yup, no CDs back then kiddies)

I have my theories engieeringwise on what causes it. It will not show up on a normal THD reading but I think it will on a TIM reading, but I do not have the equipment for that, and I am not sure exac6tly how to run that test. Anyway, I think it is caused by running a transistor output into a capacitor (low value) that has the other end tied directly to ground.

I used to have pretty damngood ears, and I believe I heard it mainly on Pioneer and Realistic tuners. And once I got the prints for them they confirmed my suspicion. The output of a common emitter stage running straight into a capacitor.

I did not hear it on other sources though. If you are hearing it on modern high end equipment and not off the radio you got some damngood ears. Amps have had Miller caps all these years and still do. And that would be where it is coming from with a design that is slightly off. And though I hadn't really considered it before, I say it could actually be in the speakers. If so, it will be level dependent. But more likely it is in the DAC or maybe even a preamp.
