Resurrecting this thread, because it has to.
Did an extensive test today on Gustard H10+V5i upgrade, LCD-2.1, Silver Dragon 3 cable.
Subject of comparison: gain setting -6 vs gain setting +12, volume matched "by ear".
After half a day back-and-forth with ~10 songs and test patterns, I finally settled on sub-bass test tones.
Result: on gain +12 bass extension is definitely better than on gain -6. The lower the frequency, the easier to hear the difference. On 40 hz I needed to repeat listening ~10 times t be sure I hear the diff. on 30 hz - 3-4 times. On 20 hz - it was obvious from first listen.
In all cases I was using rather low volume. On 40 hz test it would be at ~15% with high gain, ~30% at low gain.
Conclusion: high gain could help even if you are far from maximum volume. It seems to increase total power which is most obvious in bass. But I also agree, on some amps, especially portables, high gain dramatically increases noise. So there's a trade-off involved.
Repeated this experiment today with matched volume. -6db @ 100% == +12db @ 30% in Windows.
This time it was much harder to figure out the diff. Yet something was there. At first I was not sure whether it's volume difference or depth difference. But on high gain, 20hz were putting more pressure on my ears than low gain same volume. I was able to confirm yesterday's observations only after listening to 25hz first, then 20hz. Took me 2 hours. Oh, I'm likely crazy.
This also confirms that differences are very subtle, that's why cable makes a bigger diff in my system.
