Default Different Audio Design

Opinions on this, especially the 2.5W amp schem at the bottom.
http://www.intio.or.jp/jf10zl/EF.htm

When the amp is idle, and there's no(?) current flowing in either output
transistor because there's no forward bias, then the V drop 'resistance'
of the E-B junction adds to the 100k feedback resistor, so the loop gain
increases to the open loop gain. So it would seem that the amp would
attempt to hunt in this region, possibly oscillating?

Maybe a 1k resistor E to B on the output transistors would 'bypass'
this. Or should the amp be biased to work class AB.
