Well, considering typical effective resistance is in the range of 100 to 600 ohms, I think that pretty well answers it.
If you want to make a high voltage, low current SS circuit, with output transformer to match the high current speaker to the amplifier, you are welcome to do it. Kind of redundant though.

It's not easy. Obviously the 'standard' tube rectifiers are not really suitable for currents in excess of 250-300mA which rules out power amps. For preamps/cdplayers/dacs vacuum tube rectifiers should be fine but would likely drop a lot of voltage. Unless regulation is involved this may be a problem. Mercury rectifiers, otoh, are readily suitable for preamp duties.
So, why haven't i tried it? I guess i still haven't found a SS circuit deserving of all this loving care. A tube powered DAC would certainly look deliciously perverse if you're into digital.
Tube rectifiers...big, expensive, voltage loss up to tens of volts, low current, low efficiency, need heating, short life...
In high power solid-state circuits, the current is too small; in small signal ones, the voltage is too high.
And it's not like tube ampilfiers, which benefits the sound.
