The intended function of a bleeder resistor is to discharge capacitors after the equipment is turned off. Good caps can hold their charge for a LONG time. So bleeder resistors are a saftey requirement, and not really an option. The secondary function, in a 'L' first supply, is to sink the minimum amount of current necessary to reach 'critical current'. But this isn't an issue in your low L designs, since 'critical current', is never reached.By the way. I have a hard time believeing that a resitor of a value in the K ohms, shunted by a cap of at least 10 uFd, has any 'sound' at all. It's impedance, relative to that of the caps, is so high as to be insignificant.
