Gloria in Excelsis (common base VAS)

the problem with low feedback amplifier is the current circulation of IPS
to enhance this flow is sufficient to convert the VAS with common base:)

Now you can dramatically reduce the negative feedback
and have a thicker sound and airy at the same time;)

Thicker sound and airy... What does that even mean? :confused:

10 mA into each stage

I think that increasing the current that circulates in the IPS can increase the bass reproduction

consequently it is possible to reduce the negative feedback and thus obtain greater expansion of the high tones

the common base solution allows you to adjust the (same) operating point independently
