I am curious about the high frequency (ultrasonic) output from class D amplifiers. I have seen this output in tests in Stereophile. My concern is that we have always been told that most speaker damage is caused by amplifier clipping and the resulting high frequency energy created by clipping.
Is this ultrasonic energy insignificant compared to the energy created by clipping?

I gave up buying CDs in the early nineties because they sounded so harsh that I derived no satisfaction from listening to them. I recently bought a new NAD CD player and listened to many of the disks again. I think they do sound somewhat better but there is still something wrong.

I own a Musical Fidelity A5 CD player and I love it. As a subscriber to Stereophile, I never have seen a review of this CD player in Stereophile. Did they ever publish one? If so what issue? I'd like to get their take on it. Thanks!
