Most time when I try to reach that dynamic range (with my home stereoor with a professional) PA I get several problems: - Neighbors banging on the door because of the loud passages in the music. - Listeners complaining about not hearing anything in a silentpassage after 2 minutes of 100dB. - To small mainlines to get the current for powering 120dB(A). - To small budget to be anywhere near 120dB dynamic range.

While 24bit or higher is nice for processing, the only reason I seefor more bits on the consumer-side is to have a higher SN-ratio. Butmost consumer electronic is worse than noise of 16bit dac...
