As I have mentioned, I have nothing against Class D (I was promoting and selling B&O's ICEPower before it even hit the mainstream). Just not a fan of Class D in combination with RAAL ribbons, and that is based on feedback from the designer of these ribbons, many hundreds of customers, and personal experience.
I'll share an interesting story... My father suffered from a horrible case of tinnitus. There was one room in the old house I grew up in that aggravated his condition to such a degree, that he couldn't even be in this room for more than 5 minutes. To the rest of my family, we couldn't sense anything and it became a mystery to me. I set out to determine what was the cause of this (his tinnitus acted up even if we had music playing in the room).
For one of my visits, I brought with me some measurement gear capable of up reading to 40kHz. Sure enough, compared to other rooms in the old house, there was quite a bit of noise in the 30kHz region. Our dog Willie also avoided this room... I quickly realized my father wasn't imagining this, it was indeed measurable.
Turned out the culprit was an old CRT TV that while plugged in behind a mess of wires, was never even used. I am not an audiologist, but the one my father was seeing agreed that this was very likely the cause and he had come across issues like these many times even though on the surface, with hearing loss, it doesn't make much logical sense.
We ended up throwing that old TV out and sure enough, my father had no more issues in this particular room compared to other rooms in the house...
