None of us hate you.....we're just sitting at our desks scratching our heads....thinking "WHAT".

AFAIK.....there is no such tool to do what you're asking. Raising the volume without making it louder kind of contradicts itself. That's exactly what the volume control does....raises the volume up or down to the desired listening level.

So if your volume is set at 4....BTW I keep mine at 8 and it's perfect for all my listening needs.....then that's where you keep it. There's nothing else you can do.

Good luck.
