Hi Wombat! Now we find some common ground: although having read Michal's published paper (I've given the link previously) on his objectives & methodology in designing the Brokkly gizmo (it's not *-just-* a DAC after all), he does state that selecting the analogue volume control option (digital also available, -*if*- one can enter the menu system!) introduces some 2nd harmonic distortion - he claims that this is less than that introduced by the volume control on most preamplifiers, & the logic in using it is only if one were concerned about the "lost" bits caused by the digital alternative, which as Julf has pointed out are not going to have an audible effect in practice. For myself, I wind the Transporter (digital) volume control down about 9dB, & leave the Mytek on "bypass". With this setting, the Mytek's volume control, which I also set to digital mode, only affects the balanced (so that I can make the lead long enough to sit down... ) headphone output for my HD800S cans which are my reference transducers over my amplifier + loudspeakers by a country mile I may thereby escape any euphonic effect from the analogue stage which is stated to be caused solely by the use of the analogue volume control, but to be honest I can't hear a difference anyway. The kiddies made no reference to music or even ancilliary equipment, so it seemed like an electronic fishing trip to me. What on earth did that one commentator expect to achieve by up-sampling an already digitised signal to 384kHz?? He still received support from others though for this weird suggestion. I don't think that they'd last long on this forum! :D Did you notice that no mention was made of music in the entire piece? It's quite amusing in retrospect. Sorry that I was grumpy - I'm having a bad-back day, not that that is really a sufficient excuse (hence the apology... ).
