In circuits where gain is adjusted by changing feedback, increasing gain decreases feedback. Feedback is wonderful in that it makes everything measure like an Objective 2. Feedback is also wonderful is that it makes circuits work that otherwise wouldn't. Feedback is also bad in that it deadens the sound and collapses the soundstage.

If you have a choice and your volume control has enough room, running higher gain almost always sounds better. There are some exceptions. I've heard amps were the higher gain setting resulted in livelier sound, but also spazztastic treble.

Makes good sense, thanks for that!

It's all stuff for accountants, isn't it? Gain and loss?

As I've picked it up, over the years, from various forum contributors,  In theory...

Gain is something that happens at the input, to ensure that there is enough, but not too much, signal for the amplifier to do the needful with and

Loss (otherwise known as attenuation) is how we ensure that the amplifier's output is listenable not deafening.

But, I have been told, in practice, it might not be like that at all: it could even be just different ranges of attenuation.
