I had the idea of an preamp option in the equalizer, because of the following situation:
I often get to the point, where I'm just happy with my equalizer adjustments according to my headphones. But when I listen to a song with overly boosted low frequencies by chance, i'd have to adjust only the low frequecies in the EQ and therefore loose my earlier setting. I'd rather reduce the overall EQ-boost whilst keeping my earlier adjusted "Hi-Fi" sound.
Alternatively I could really get used to some customizable (and savable) EQ-settings..
I hope this post doesn't just end up being put in the repost-channel, forwarding to an assumingly similar post which then nobody is able to comment.
