Seems that the SRM252 amp hasn't got the strongest power supply
(guess that's mainly because of the internal high voltage generation circuit)
so it should work better with the less demanding earspeakers, or?
In comparison with the SR202 (120pF incl. cable and 132kOhm at 10kHz)
the SR007 has 94pF and 170kOhm and the SR003 just 44pF and 360kOhm.
