If your point is right you are not missing something. I do not have the gift to remember everything i read. Thats why i am discussing it(digital vs analog volum) here in this fourm whre there are peaple with more education, training. Using "my" calculator. Multiply 16bit decimal value 65535 with 0,35(%error) and converting it back to binary it only affect the last bit. Just likes as you explained. The higher wordlength and sample rate we have the less potential error distortion we get, when reproducing analog audio. If the uppsampling device is very good, or the audio line are correctly implemented - computer - software - dac - dac - amp - speakers. If you add wordlength and sample rate it can couse to much peak and distortion to treble and bass. Potentially. Every time we are using digital volumecontrol, i quote from the guide(dont know if it is allowed?): To apply gain or attenuation to a digital audio signal, a multiplication is performed on each digital sample that collectively create the digital audio signal. If we use 24bit/96khz in todays audio, we stays within the potential of 0,5% error, presumably. And only the last digit will be affected. But, if that is not trough ? I dont know. Peaple cant hear no difference. Transporter use digital volume(it must be good). I will use the analog volume and recommend the other users in this apartment to also use analog volumecontrol later. It is nice to know that software player - SB3 - is at 100% volum. It have being interesting and fun to discuss. -- eiret ------------------------------------------------------------------------ eiret's Profile: http://forums.slimdevices.com/member.php?userid=11521 View this thread: http://forums.slimdevices.com/showthread.php?t=38233 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
