Man talk about being lazy. I was too lazy to disconnect my Krell downstairs because of how heavy that thing is and the clutter.
So I just went and bought a used Rotel RB-1080 Power Amplifier
and connected it to the the computer. It works! I see no downgrade of quality. Everything is clear, sound stage is wonderfull, good separation, and warm and filling sound.
I see no downgrade in audio quality when using Windows volume control. Good thing my keyboard (Logitech G510
) has a volume scroll and mute button.
Thanks for all the help guys! Now I just need to get a pair of B&W 804D speakers
for the computer and it'll be done.
