They don't hurt. They can increase stability and for this amp, that's a good thing
Another suggestion: There isn't a need for the ground plane you have there. You could run wide traces back to the star, especially from the 2 bigger caps on the output stage. Right now, the front end decoupling ground trace is wider than the output decoupling.
Also, look at making the output trace wider. This carried all of the current the amp provides.

lineup said:My guess is that roender thinks about keep a distance
between hot power transistors and heatsink and the electrolyt capacitors.
Higher temperatures will shorten the life of lyt-caps.
Yes and no. The main reason is to keep as small as possible the ground line between decoupling capacitors, as that line is highly polluted with half waves rectified output signal
Take a look here: http://www.diyaudio.com/forums/swap-meet/185970-boards-sym-v2-flodins-new-symasym-5-a-3.htmlAnyone with an inside line an a set of these PCB's, i would like to get my hands on a pair...
