Ah ok , your active monitors they have some sort of volume/gain I assume so that you can pre set a sane level . And as most of your music is 16bit anyway ,you could get rather low in volume before it "eats" bit 16 ( volume is implemented as 24 bit ) and then you would not hear that as the volume is so low , given correct gain . As the DAC chip in TP probably is of some sort of delta sigma or "one" bit type it's linearity is good all the way down you just gets closer to the noise floor . Another practical effect no is that no audio equipment is really 24 bit anyway sn ratio is not 144dB it is usually in the 100db range and the transporter is excellent here is not closer to 120dB but my piont is that at best you can get 20-21 bit practical resolution out of a DAC many simpler ones represents 18 bit practical resolution . Wonder if transporters volume algorithm just truncates or use dithering if it dithered when changing resolution it would be perfect and I would not be bothered at all ( like my meridian setup which uses some kind of combination of analog and digital volume with dithering ) . I don't think there is any practical loss of resolution to be bothered with with a 24 bit volume controll given sane gain on the analog side . And besides the noise levels of recordings is such that bits >20 is just garbage anyway even in the best of circumstances as ADC has the same problems , and the dynamic range practically used is not even close , given typical background noise and sane listening levels how much dynamic range do you have use for . Sorry for the off topic I find this interesting :) If you are really nerdy try this , get a bunch of test sounds recorded at very low levels like -70dB -80dB -90dB -100dB -110dB -115dB etc keep your volume at your "normal" listening level , sit in your listening position can you hear any of them ? You could re test with volume at what is " normal " for a very good recording like classical and also your " party volume " the highest you practically use . You could also,test at full volume to se where the noise floor is but this is less interesting as you don't listen at this level . For a ->110dB signal you probably have to walk rigth up,to the speaker and put your ear close to a driver to hear it .
