Impedance differences – PS Audio
https://www.psaudio.com/pauls-posts/impedance-differences/
In the first case of doubling the amp’s input impedance, we won’t hear any difference because nothing in this chain affects frequency. The amp’s input impedance must be high enough to not load down the preamp, but aside from that, not much else matters. That’s not true when it comes to a device such as a phono cartridge.

(CD, tuner) (preamp) Z o Z i Fig. 1 With : Z i / Z o ≥ 10 (1) Most hi-fi gear is based upon this impedance scheme : Low output impedance, high input impedance. The admitted minimal ratio for proper compatibility is 10 or higher, as stated above.
Understanding Impedance - Sound on Sound

The output impedance of a device and the capacitance of its connecting cable form a simple first-order low-pass filter, producing a 6dB/octave attenuation above a certain frequency. However, you need either quite a low output impedance or quite a long high-capacitance cable to bring the turnover of this filter into the audio band.

Every electronic piece of equipment has a impedance. Audio or RF. They need to be matched so power can transfer from one stage to another. If it’s not matched, it becomes inefficient. It looses power thru heat! A radio tuner does matching of RF devices. It’s …
Impedance Matching of Audio Components
http://hyperphysics.phy-astr.gsu.edu/hbase/Audio/imped.html
While impedance matching of a microphone to an audio amplifier is not the problem it was in the early days of high fidelity sound reproduction, there are some considerations that still apply. In practical terms, the modern microphone needs to deliver optimal voltage to the preamplifier, and not necessarily the optimum power that would require ...
