IC Rolling: LF351, LF353, HA4605, NE5532, RC4558, 1H5011, and LM339

I opened up my Sound Workshop Logex 8 mixer, and I discovered to my surprise that all IC's are socket mounted. According to the spec sheet/advert, these are the IC's that are in it:
LF351, LF353, HA4605, NE5532, RC4558, 1H5011, and LM339

I'd like to improve this mixer as much as I can without doing anything drastic, and since all the iC;s are socketed, changing them is a snap.

So, what could I upgrade?

Here is a link to Tangents opamp review http://tangentsoft.net/audio/opamps.html
You may be able to swap out the NE5532 for something with lower noise and wider bandwidth, but I am not sure it you are going to notice anything quite significant. If anything you can use any new opamps for a headamp.
Be careful with sourcing opamps, many of the the higher quality opamps on ebay are knockoffs.
