Every 6dB of gain equates to a doubling of voltage; as such, a hypothetical amplifier with a voltage gain of 30dB will increase voltage by 2^5, or by a factor of 32. For unbalanced inputs, the THX standard gain level is 29dB; utilizing balanced inputs decreases this to 23dB, though naturally the output of the preamp is boosted by 6dB under this scenario (i.e. …
Calculating Gain for Audio Amplifiers (Rev. A)
https://www.ti.com/lit/pdf/sloa105
audio power amplifier should be as large as possible, to have a high SNR. Conversely, the gain of the audio power amplifier is set as low as possible. If the audio power amplifier’s gain is set too high, then it amplifies the noise floor, along with the actual wanted signal of the CODEC or DAC.

Ultra-High Gain Audio Amplifier Sometimes called the ‘‘JFET’’ m amp,’’ this circuit provides a very low power, high gain amplifying function. Since m of a JFET increases as drain current decreases, the lower drain current is, the more gain you get. You do sacrifice input dynamic range with increasing gain, however. 5
Gain vs Volume: Knowing the Difference Could Change …
https://www.musicianonamission.com/gain-vs-volume/
Most guitars had both a gain knob and a volume knob, meaning that you could send a ton of gain into the amp, overload it, then keep the volume reasonably quiet with the volume knob. That’s how guitar distortion was created. Overloading the guitar amp with gain so that the speaker can’t process the guitar cleanly.
