It's more an industry problem than a designer problem. It's mainly due to there being only informal signal level "standards" for non-professional audio gear, and reaction to changes in technology:I had an old NAD amp like that. Think it was a C320BEE. Had to use 26dB of attenuation (via Russ Andrews plugs) and it was still less than 9 o’ clock on the volume control for normal listening levels. What are these designers thinking of? Just crazy.
