This is the opposite of what the "theory" is.And how does it sound?
Hmm.. weird can't find A30 manual, didn't yours come with one? Here's my guesses:
"Hi or Lo working voltage" - hd6xx; Nominal impedance: 300 ohm so I'm guessing hi for full sized headphones? It really makes no audible difference between the different settings?
Increasing the gain increase the noise (noise as in distortion added to signal), so you want to have the gain as low as you can while getting the volume you want.
That doesn't really matter, in theory, might be best to max your amp's volume (the volume pot is basically a resistor, so max volume bypasses it, but rather insignificant in reality) and manage your volume through your pc, but that increases the risk of having your pc sound for some reason increasing and blasting volume though amp & headphones & ears... So likely not worth the risk; plus just try it, if you can't tell the difference it really doesn't matter now does it?
You should use the volume knob for your volume (analog) instead of digital volume (computer).
You should set the DAC (D30) to max inside of windows at all times and in your applications, then you control the volume with the knob.
You turn the "gain" up when the volume is at max and the volume is too low (which increases the amount of power by the multiplication of the gain).
It really doesn't change the audio at all haha... I've gotten a replacement A30 from Topping as my first one was faulty, and both of them didn't change the audio quality at all. I've also seen someone else mention on a Massdrop discussion that it didn't change anything for them as well. I guess if thats the case I should just leave it at low... haha
And sweet, the settings I've been using are max pc audio, Low and 0dB gain and 3/4 on the volume knob which seems loud and clear enough for my ears
That's about what I use on my setup (D30/A30).
I have also used the A30 now with some other DAC's (Schiit Fulla2 DAC-Out, SMSL M8, SMSL M8a, Schiit Modi Multibit). It sounds great with all of them and I continue to listen it basically all day every day!
