I'm running LMS 7.9.3 on my QNAP nas.
Whenever i'm turning the volume up to about 90 or 100%, the music starts to distort.
It is easy to overcome by turning up my amplifiyer, but I find it a strange bug nevertheless!
Is anybody familiar with this kind of behaviour of LMS?
I'm using a Harman Kardon hk3390. But its nowhere near it's maximum volume. The problem only appears when i'm using my squeezebox.
Do you find this happens with all tracks that you play at 100%, or possibly just some? I think I have experienced something similar, in that I perceive when playing tracks that were mastered badly in order to sound "loud," and contain a lot of clipping, that the distortion seems worse when setting my Squeezebox volume to 100%. I am using a separate DAC, but possibly the result is the same. I found that the effect is mitigated by setting the volume to 88%.

Sensitivity is a measure of the magnitude of input signal need for the amplifier to produce full output, at maximum volume. This tells us what signal sources the amplifier can handle
A pair of in line attenuators is called for here I think (assuming the OP is not plugging into the Phono input

I thought the same then I checked the sensitivity of my Audiolab 8000a and it quotes 100mV so not entirely sure what that means. My amp has the same sensitivity for all line level inputs.

What happens when you set output to 100% fixed in LMS?
It's not the same as ramping the volume up and down with the remote control.

It requires a signal of 100mV before it starts amplifying it.
The Denon is less sensitive than the Audiolab, but both should be capable of handling full voltage output from a Squeezebox Receiver, as both amps were released after CD players had become the normal state of affairs.
My NAD C320BEE has an input sensitivity of 220mV, and can handle a maximum 6V input.
It's interesting that the other two manufacturers do not publish a maximum input figure.
