High Input Impedance and Low Output Impedance in Op …
https://www.apogeeweb.net/electron/high-input-impedance-and-low-output-impedance-comparison.html
Why does an op amp have high input impedance? Op amps need high input impedance because they are voltage-gain devices. In order for voltage to drop across the input, the impedance has to be very high, as ohm's law states, …
Is there any standard for the input impedance of an audio ...

Generally the input impedance to an audio amplifier is 'high'. That is, high enough to be driven comfortably by any audio source output. But of course, without a proper specification, you are taking something of a gamble. 10k to 100k is the usual sort of range we find, though some can be less.

Stickman451, you are correct as is Jmcgrogan2. Its easy enough to design a solid state amplifier with a high impedance input (100K); they could even make it switchable if they wanted. Although our preamps are vacuum tube, they can drive even 5K with ease (they are designed to drive 600 ohms).
What is Impedance in Audio? Input and Output …

This is a high impedance small amplifier circuit. It can give power output about 1W with connecting to a 9V power supply. The advantage of this circuit is using dual Darlington transistors. So they have more size of input impedance …
Impedance Matching of Audio Components

Impedance Matching. In the early days of high fidelity music systems, it was crucial to pay attention to the impedance matching of devices since loudspeakers were driven by output transformers and the input power of microphones to preamps was something that had to be optimized. The integrated solid state circuits of modern amplifiers have largely removed that …

To increase the efficiency of the resistance Causes the input impedance of this circuit, to increase to about 6 magma ohms. The output impedance when the signal comes to around 500 ohms. What is this circuit suitable for? This FET preamplifier circuit is suitable for sending signals from the preamp to the amplifier circuit that uses long wiring.

Hi-fi equipment with phono connectors usually employs the voltage matching concept, with very low output impedance and much higher input impedance (although rarely as high as 100kΩ). Typical signal levels vary between 250mVRMS and 1VRMS, although CD and DVD players are usually specified with an output voltage of 2VRMS. Microphones & Preamplifiers
