I guess people are thinking why would either not perform well? And "what do you mean by clear sound?" in terms of noise, distortion, bandwidth etc?

The OPA627BP would definitely make your wallet go jingle-jingle much louder than the LME49990. The latter was killed by TI, so good luck finding one. You may want to look at the OPA1612 or LME49720.

Is this the sound card?

Essence STX II 7.1 | Sound Cards | ASUS Global

If so, I'd suggest better headphones or speakers, I doubt very much the card is the problem.

Have you looked at the data sheets for those parts? That would answer your question. They're available at www.ti.com
