Most AC3 channels do have a lower volume due to the fact that the dynanic range of AC3 is much more than 100dB. This is much more than you can do with Mpeg Audio and raw PCM at 16bit[1].
You know that you can feed floating-points into mpa and get the same out and there is also an extension for mc, so in theory you can get nearly the same dynamics with mpa as with ac3, but usually tracks are not mixed this way and as nearly no receiver handles mpa, it gets decoded to PCM anyway, so practically you are right.
OK, usually I do not feed my AV amplifier with mpa even if it can decode this. This because it can not detect this automatically as ti does it with PCM/AC3/DTS .
Do you have a mpa sample which demostrate the possible dynamic range? With the help of the bitsteamout plugin it is possible to forward the mpa to an AV amplifier/receiver.
