lol . smackdown.... i was thinking the same thing. lol no thats ok. i can admit if im wrong. i have learned some things from here. most of it is just sorta reinforcing what i already knew, but there are aspects of audio like a record player and its parts that i am not the most knowlegeble on. And some stuff that i might read in someones post or review when they are describing the sound and i might be like wtf is that supposed to mean. but i mean, go to the library and check it out and see what you think for yourself. But the 30 bucks was worth it for me to fully understand ( or so i hope ) how a servo sub works and about analog stuff and like that. Alot of it is basics that im sure most of us know but it still has some things that i did not fully understand.
