This tread: "Leo and his 420V 6V6", now on its 5th page, got totally off track (after page 2), so it's time to start a new thread…
The assumption here, which caused the previous tread's disruption, is:
Although an increase of 3dB represents a doubling in power, an increase of about 10dB (10x more power) is required, before the sound subjectively appears to be twice as loud. The smallest change one can hear, is about 3dB. Or in other words, an average person, with everything the same (specially speaker's efficiency), can barely tell loudness difference between a 5W amp and a 10W one; and a 50W amp will be perceived to be twice as loud as a 5W amp !!
Therefore, an output power increase from 14W to 22W, with all else being the same (including the speaker), cannot be heard by an average person.
Additionally, I read somewhere, that an average person can perceive 1dB increase in loudness for a SINGLE TONE, but not for a complex signal like music.
