Did some experiments on the fuse of my amp... I replaced a 500mA 250v
fuse with a 1.6a 125v fuse and found the sound much improved. Then I
decided to replace the 1.6a fuse with a jumper made of a silver
paperclip, and found the sound improved much further. Then I replaced
the paper clip with silver solder, and found it improved further
(though I'm less sure about the solder being better than the clip
overall...).

If any of these had any effect on the sound, your amplifier has some kind of
power supply defect and should be repaired.
