   I have need for a low distortion AF preamp, preferably in a IC

   good application for an op amp?  


I'm sure someone out there will disagree with me, but I think you
should consider using products from PMI (precision monolithics inc).
They produce several audiophile-grade preamp chips, as well as op-amps
that are tweaked for various audio gain and filter applications.
Their parts find their way into much of the studio gear used to record
much of the music you hear, so you'd better hope you like their sound.
Analog Devices also produces several well-regarded op-amps for audio
use.  PMI has a small publication with usefull circuits for their
products, called the 'Audio Handbook' (or something like that), as
well as a giant full-line book with less-detailed ap. notes.  I've had
good luck obtaining free data books from both companies (actually, AD
just bought out PMI).  Try calling 800 information and get AD's
publications office.
