It is funny the fantastic sounding class A amplifiers (electrons flowing all the time trough the active amolifiing device) have been acused of high power consumption compared to power output, (low power efficiency).
And now we are surrounded by millions of power hungry computers on all the time making the miracle of internet possible. And no matter if we press play or not the power consumption is almost the same and it is high.
A recording cassette Walkman will only consume power when one presses the rec button, it will start recording instantaneously, almost at the speed of light. The sound quality is so lifelike. A disadvantage is possibly more wow and flutter that the good sounding low wow and flutter.
Example setup:
Sony F-96 moving coil omnidirectional mic at 1 inch distance - Sanyo TRC- 2500 excecutive talk book cassette recorder
It's power amplifier would not be in class A but its recording amplifier should possibly be.
It sounds very real.
Having this little 100mA current at 3 volt consuming Walkman in front, you can hear a recorded voice coming from it. Turning your head the soundfield from the reflections of the room changes and the brain knows the voice always comes from the same position. No matter what you do even if you walk out of the room. Is it more real reality than virtual?
