I recently put together a comparative table of audio op-amps for the Bass 
e-mail list; I thought you might find it useful:

Manufacturers:              Electrical Characteristics:
-------------               --------------------------
OP,AD = Analog Devices      Noise units are nV/Sqrt(Hz)
OPA   = Burr Brown          GBWP = Gain-Bandwidth Product
HA    = Harris              THD  = Total Harmonic Distorsion
LT    = Linear Technology   Please note that THD is measured
LM    = National            under different conditions by
NE    = Philips             different manufacturers, so it's
RC    = Raytheon            only orientative.
* Means 'highly recommended' in the rec.audio.* FAQ.
Refer to manufacturers' datasheets for complete data and
measurement conditions. These datasheets can be downloaded
in PDF format from the manufacturers' www pages. A list of
manufacturers with links to their home pages can be found at
