I wanted to entitle this: "Bonnie Baker Reveals All" -- but I do read her column in EDN religiously -- some reasons that you single-supply amp may sound better when used in Inverting mode:

No opamp at all is better.

There are 2 advantages of opamps:

1. no DC shift
2. High efficiency

Since they are used with coupling caps the 1'st one is out.
Second one may be traded off for sound quality in power amps, or absolutely have no meaning in preamps since their power consumption are nothing against what power amps consume.

However, there is the 3'rd advantage: imaginable simplicity of design that is melting down as soon as you design something better than can be bought in the nearest store.

The Devil is not so terrible as his math model is!

Well if you can get away with an inverting configuration then you do not need a rail-to-rail input opamp.

I don't know of any common "audio" use opamps that have rail-to-rail input stages either.
