"Sound problems can *always* be fixed without tone controls"
There’s more to life than serving your stereo. Not everyone can afford a dedicated listening room, or different speakers for different uses. Also, how, exactly, do you fix issues of the recording engineer making choices for speakers that were trendy a decade ago?
The purist ideology falls flat more often than not. Also, why NOT use tone controls if they are otherwise transparent? Why should I go out looking for a new preamp/amp/power cable if the tone control is right in front of me??
Why on earth are super expensive cables OK to use to adjust the tone, hell even buying new speakers and amps, why are those OK but not tone controls?? Makes no sense to me.
