I recently purchased a Schiit Asgard 2 headphone amp which I use with my PC. I have it hooked up to my PC using a 1/8" to Dual RCA cable, output from the headphone jack on my PC.
I’ve read before that the volume in the source (my PC in this case) should be turned up to 100% and then the volume from the headphone amp adjusted accordingly. However, when I do this I get distortion, even with the Asgard 2 at a relatively low volume level. I have found that it sounds best when both the PC and the Asgard volume controls are somewhere in the 50%-75% range at the same time.
Is there some sort of general rule of thumb that should be applied to setting the PC volume control? Perhaps either this 100% PC volume rule is incorrect, or this is a sign that my PC is a poor audio source?
Any general tips that anyone can provide would be greatly appreciated. I am a noob with this stuff.
FYI - I am using a pair of Grado SR225i headphones and my PC has Creative X-Fi soundcard with all DSP and extra sound ‘enhancements’ turned off.
