If, for example, you have a source with up to 4.4 volts output then a resistor based passive pre-amp will have all the drive of an active or TVC (Transformer Volume Control) pre-amp. Whilst being more transparent than the active and having better bass and treble than the TVC.
Voltage alone does not make a circuit, you need current too!
OK then, for example a source that can deliver 4.4 volts into a 200 ohm load will give you enough current to make a resistor based passive pre-amp the highest-end pre-amp you can get in that system.
Happy now?
