Hi Gasho,
Please keep in mind that the "Class A" switch only increases the bias current. The switch should be labeled "Make Run HOT for no reason". At the higher bias current, this is still an AB amp. It just transitions to class B a little later... and runs hot. This is typically rough on the PC board connections.
Besides, there is much more to good sound than the level of bias current. Circuit design and power supply design comes to mind here.
