What is an audio buffer? – PS Audio
https://www.psaudio.com/askpaulvideo/what-is-an-audio-buffer/
Lets just say, we’re gonna use two 6922 tubes to make a buffer amplifier. You have the plates of one tube feeding in to the screens of the other tube. The first tube, is gonna give you the high voltage, the second tube, is gonna give you the high currant. In most cases, you don’t need anymore then 250MV going in.

Audio amp need to drive a speaker that is very low impedance ( 8Ω). You need a stage that can drive such a low impedance load. CE stage usually has very high output impedance to get the gain, so you need CC to buffer the high impedance CE stage in …

This is a review and detailed measurements of the VTV Purifi class-D amplifier with the optional Weiss OP2-BA Op-amp (buffer/input gain stage). It is on kind loan from a member and costs US $2,090. I just reviewed the same amp but with SIL 994EnH-Ticha Pro buffer so you can compare them.
operational amplifier - how to split audio with buffers ...
https://electronics.stackexchange.com/questions/197827/how-to-split-audio-with-buffers
This is a typical powered headphone splitter/amplifier. It is a single gain amp to multiple non-amplifying buffers. The 5.1kΩ Resistors represent the load. As it will be in parallel with your actual load, they won't affect much. Notice, no pull-down resistors needed between the Gain Amp and Buffer Amps. This is as generic as it gets. Share
VTV AMPLIFIER Stereo Purifi Audio 1ET400A - Which …
https://www.audiosciencereview.com/forum/index.php?threads/vtv-amplifier-stereo-purifi-audio-1et400a-which-input-buffer.25852/
I purchased the VTV buffer with Sparkos SS3602 op amp which I found to be much more agreeable. At the time I was driving the amp with Topping D90 thru a Schiit Freya + using the passive volume control. I also tried a few other op amps, OPA1612, OPA627, and Burson V6 Vivid, but I preferred the Sparkos to any of these.
