Is there a statistics of ...

how Audiogoners' CURRENT MAIN systems consist of with BRAND information plus following?

(1) Source: analog or digital or both
(2) Pre: yes or no, if yes, tube or ss
(3) Amp: tube or ss, integrated or not
(4) Speaker: stand mount or floor stander

Don't mean to show which brand or setup is superior, just curious.

For example:

(2) Pre: no
(3) Amp: SS / integrated / Bryston
