I'm looking for an amplifier that can do extreme dynamic range. To get that, usually you buy a huge amplifer that can do 1000w (rms) for every speaker, or something like that.

However, I don't need a 1000wrms amplifier. I need an amplifier that has a high rail voltage that can do 1000w peaks for short durations, and a modest (everything else) that can do maybe 100wrms.

Is there such a thing?

The closest I've found (I think) is the Mosconi Pico amplifers that specifically state they are designed for music and should not be bench tested with tones. That is the kind of verbiage that hints at the kind of thing I'm looking for.
