Check out Hornshoppe's 'The Truth'. Active. No gain. Sounds astonishing.
LDR Active Preamp - does it exist?
I am using passive LDR (Light Dependent Resistor) volume control LightSpeed Attenuator. As much as clarity and all the good stuff about this little preamp, I wish I can have some gain for my low sensitivity amplifiers. Is there any existing active preamp using LDR volume control?
