I've got two technical questions which I hope someone here, maybe from iBasso can answer:
1. I was wondering if the DX50 was featuring a digital volume control, although the Wolfson 8740 doestn't seem to have this feature (http://www.wolfsonmicro.com/products/dacs/WM8740/) but e,g. the 8741 has digital volume control listed on the web page "Digital volume control in 0.125dB steps with soft ramp and soft mute" http://www.wolfsonmicro.com/products/dacs/WM8741/
So is the volume control on the DX50 digital or analog?
2. If volume control is digital, according to this info here (http://thewelltemperedcomputer.com/Intro/SQ/VolumeControl.htm) the full 16 or 24 bit word length - some call it "resolution" is only
put out, when the volume is set to maximum, here: 255. Every lower value will result in a possible change of data, e.g. if the volume is set to 90%, every digital value is multiplied by 0.9 before converted, possibly causing quantisation errors.
So the logical conclusion is: If the volume control is digital, should I then set it to maximum (using line out and an amp of course, not HO), because only then I get the unaltered data from the source converted to analog audio?
Further thinking about it: As if it's not pointless enough to listen to 24 bit files, listening at very low (digital) volume will result in a drastic reduction in "resolution", or better dynamic range,
e.g. a 24 bit file becomes 12 bit at 50% volume, right? ;)
