B&O system head units can be turned all the way up with no clipping.
yes ,but you are forgetting about the modified fletcher munsen curve thats applied. once you get past about 70% on the volume scale, the curve becomes more present. so even if you arent clipping (which i havent tested on the b&o) the eq curve set in place will modify the original signal to the point where there is substantial audible differences, and then trying to make up for the loss in frequencies through a sound processor makes the sound become more "manufactured" instead of natural. besides, its never good to run things at 100% you then lose any chance of dynamic heardoom in the sound system. most sq competitions will be judged around 25-30% volume depending on how loud i want to hear the music that day. but never above half volume. even with aftermarket equipment, running everything at max, gives you no room for improvement. and then the audible issues you will have.
