TDA1308 if you can still find it... saw a comparison table yesterday... these were also the chips that swung the highest level output
If one can believe the application notes at Ti, most opamps can be used off a single rail supply.

An externally hosted image should be here but it was not working when we last tested it.

I know http://www.elfa.se/en/
has got TDA1308
TDA1308 is a dedicated little IC for Headphones applications.
I have had the idea to order it, and show my brother
how small a fairly good Headphones-Amp can be made
with modern IC technology.
Philips Datasheet:
http://www.nxp.com/acrobat_download/datasheets/TDA1308_A_4.pdf
The TDA1308; TDA1308A is an integrated class-AB stereo headphone driver contained in
an SO8, DIP8 or a TSSOP8 plastic package.
Features:
Wide temperature range
No switch ON/OFF clicks
Excellent power supply ripple rejection
Low power consumption
Short-circuit resistant
High performance
High signal-to-noise ratio
High slew rate
Low distortion
Large output voltage swing
As Nordic says, it has high output voltage swing.
Think it would be perfect for 2-4 battery operation.
3-6 Volt DC
lineup
As you can see in ELFA catalog
( english version http://www.elfa.se/en/ has got prices in Euro € )
If buy 10 pieces, you get to pay 15.80€.
You will have to add VAT and of course some for transport.
Buying 100 will cost you 80 Euro.
You could then supply the whole of South-Africa, for a couple of years

Gentlemen,
The easiest solution ist to get hold of an elder Acer CD-ROM reader, it contains a Philips TDA 1038, other CD-ROM players from Samsung, contain PT2038, which has same pinout and characteristics.
I used such chip to repair a Noxon2audio internet receiver. I used a small saw and cut out the amplifier part.... it works on 5 volts and has very low hiss.
good luck
