I have active speakers connected to my integrated sound card.
will upgrading to a better sound card change the sq?
I would guess a sound card like the Asus Xonar DX or D1 sound card (used $50-$65), with their CS4398 DAC chip, should offer some audio quality improvement over on-board audio.
Or maybe get the Hifimediy Sabre USB DAC, $50-$60
Probably true, but the OP didn't say what his computer is, laptop or desktop, PC or Mac. A few years ago I'd have said without reservation that you can always improve in the integrated sound card. Today, there are a few that are good enough that the investment isn't always worth it.
So, OP, what to you have?
