Goomz, it might be a good idea to ask yourself exactly what you mean by "max volume" and why you want it. The only input signals whose levels don't vary are sine waves and pink noise. For anything else, and I mean absolutely anything without exception, the instantaneous level of the signal will vary by at least 100:1 between the softest and the loudest, and for lots of material - classical music being probably the most extreme - the dynamic range (ratio between softest and loudest) may reach 10,000:1. I'm referring to the level of power the amplifier sends to the speaker. So, what does "max volume" mean? Your call.
