I am actually using that combination with the components 2SA970/2SC2240 and 2SJ554/2SK2955. It is absolutely temperature stable - using 0.1//0.1 ohms = 0.05 ohms as Re. They are even used in a bridge configuration driving Quad ESL63. And there are no stability or temperature problems in my output stages. And it sounds good too.

I have only measured frequency linearity with sweeps and a RMS voltmeter and it is straight up to 20kHz (max. on CD ;-) . So IMHO this combination should not be dismissed.

But of course it depends on the type of MOSFETs.
