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.
Amplifier Input Impedance - High-End Audio Discussion Forum

Preamp : Reimyo output impedance is 560 ohm , Power amp: AES superamp AE 25 input impedance is 150,000 ohm . This gives ratio of 267 times . Does it mean I have a total mismatch ? Absolutely not! The 10X rule is a MINIMUM suggested requirement. Some manufacturers, like ARC, recommend a 25X to 30X MINIMUM impedance relationship.

For instance, if you connect a microphone to a mixer, your microphone has an impedance of less than 200 Ohms. The input impedance of the XLR balanced connector of a mixer or preamp is between 1500 – 3000 Ohms. This ensures an excellent current flow between the two devices.

Most power amplifiers have input impedances of at least 20kΩ and higher. Our own power amps, for example, have 30kΩ input impedance, high enough to never reduce bass levels of capacitor coupled preamplifiers, even if they are the vintage kind.

What do you mean by the input impedance is greater than 4k?CD players produce an average of 2 - 3 volts signal. Please check your figures. If the output of the source has an impedance of 10k then it will run into an input load of 10k or greater. Most amplifiers are set at 18k or higher. •••
Output impedance – PS Audio
https://www.psaudio.com/pauls-posts/output-impedance/
If the input impedance of your power amplifier is 10k then the output impedance of your DAC or preamp feeding it must be at least 1k and better if it’s 100 Ohms or less. If it’s 100 Ohms you’ll only lose a tiny amount of signal at the junction between the preamp and the amp – 100th of what you are sending, just for understanding sake (not entirely accurate but you get …

The right answer is to go DAC>Sys>Loki>Hafler. The reason is that the Sys has a very high output impedance - up to 5K ohm - while the Loki is much lower, at 75 ohm. The Hafler has a moderately low input impedance, 22K ohm. The …
Gryphon Audio Designs Essence preamp and power amplifier
https://gryphon-audio.dk/wp-content/uploads/2019/08/HIFI188-Gryphon_LR.pdf
In Gryphon Audio Design’s world, Essence is the starting place in its pre/power line. There is a long way to the top of the Gryphon tree. Essence is the new preamplifier and power amplifier line from the Danish brand. It joins the Scorpio S CD player, the Diablo 120 and 300 integrated amplifiers and possibly Mojo S loudspeaker at the start
