I have a dilema and I would like to hear your recommendation for best audio dual SOIC opamp, running at +5V only. Not much is there to choose from, but I'm sort of torn between these there:
AD823 http://www.analog.com/en/amplifiers...mplifiers-op-amps/ad823/products/product.html
LM4562 http://www.national.com/pf/LM/LM4562.html
AD8397 http://www.analog.com/en/amplifiers...plifiers-op-amps/ad8397/products/product.html
AD823 got a bad name for being too harsh and flat sounding (and hard to get one), LM4562 is picky a like to pick up interferences, not to mention still being a bit too much harsh/sharp ... (but I have few at hand) and I did not know much about AD8397, except that it could be get as sample easily.
The opamp will be used as LineIn input opamp on my X-Fi. Replacing a MC33078 opamp.
So, guys, are any of these even better that the TI original MC33078? And witch one would you recommend to install?

LM4562 should win hands down on THD numbers and just about every specification. For sonics, you may also want to give the old TL062 micropower op-amp a listen - it will run on +/- 2.5v, but it's very close to the lower Vcc limit.
Could be... how about these?
