Low Level Listening and Distortion


Would some amps sound better at lower levels due to distortion being produced at a lower sound level than another? In other words, a "clean" sounding amp (think stereotypical class D) sounds better to me at higher volumes while another amp sounds much louder than the class D at higher levels but great at lower levels, which I assume is our ears translating distortion into "louder" in our heads. Is it the job of a preamp to be sure the amp sounds the same at all levels or is this just impossible to make the sound that linear? I have one of the newest GaNFET amps from a well-respected designer/manufacturer playing at the moment and it sounds boring at low levels but good at higher levels. Not surprisingly it also sounds quieter at the same matched volume levels (using white noise) than the tube amps I also have. I hope I explained my question so it can be understood. Thanks.

@bigtwin I enjoy music at low levels.  It's part of my weekend routine. Wake up early, go downstairs, throw on something I really want to hear and listen for a couple hours watching football/soccer on TV. I don't want to disturb anyone in the house so I have to keep it low. My Harbeth's are great at low level listening. My Devores seem to be more amp sensitive when it comes to under 70dB...hence part of the reason for my asking this question.  It makes sense to me logically that certain amps will sound thinner at low volumes, which is why loudness buttons used to exist (and still sort of do) but I've never heard an expert like Ralph's opinion on the subject of more pleasing distortion at low levels. Could an amp be made that specializes in sound up to 70 dB? I really have no idea.

The enjoyment / volume is a function of quality of system… well, in general, there are exceptions. But, in general, the better the system, the less volume is required to be engaging. A few minutes ago I was captivated by a tune at volumes averaging 68 db. The high volume requirement is not required at al in great systems.

All I know is that a lot of people choose the Sugden A21, A21se signature because it excels at low volume listening. It is a pure class A solid state amplifier. Mine sounds excellent at lower volumes, especially driving a 10 inch dual concentric driver in the Tannoys.
