Quad Op Amp for Audio

[inman at interpath.com]

I am looking for suggestions for a standard QUAD OP AMP for
audio signals.  I guess what I need is a high speed, low noise OP 
AMP, hopefully not too expensive.  I have been using an LM837 
which works well.  Is there something better that is not 
extremely expensive?

Thanks,

Elliot

PS.  In Electronic Projects for Guitarists, Craig Anderson uses a
dual op-amp, the NE5532.  I assume this is a very good chip
(cost $1.20 from digikey).  He also uses an XR4136 quad, but
I cannot find that.
