EQ presets for stereo listening...

Unfortunately on my system i am unable to disengage the eq presets...would classical be the most nuetral?
Do you have any other options ?

Pick what sounds best to you.
Many complex electronics from the major manufacturers have a 'reset'.
Som group of unusual button pushing, usually at turn on will reset the electronics.
You should check your manual for such a setting.
It may solve your problem.
You need to tell us what equipment you are referring to. AFAIK, there is always an option for no EQ.
