A bit of a overreaction don't you think? If it 'enhances' your driving experience, what's the problem? I't's no like the sound is being blasted outside of the car.
I remember a audio-file chap I knew once saying that there was no need for graphic equalizers in stereos as it takes away for the sound the artist intended...BS.
Do you feel less 'connected' to the car because of power steering...
