Ok so I've tried googling my question but to no avail.
My question is does the volume levels at various stages in the signal path make a difference to the final sound quality? For example, you could have:
Sound Card 10% > iTunes 10% > Headphones 60%
Sound Card 50% > iTunes 100% > Headphones 10%
Sound Card 100% > iTunes 10% > Headphones 30%
I've tried experimenting a bit but without an A/B setup its a bit hard to tell. I *think* that theres a definate difference when the volume on the sound card is very low or very high, but I'm still not sure. I was wondering if anyone that knew their stuff could tell me for sure, and if it does make a difference then what's the best practice. Thanks!
