How Do You Learn?


After 5 years back into this HiFi pursuit I realize I may need to reassess
where I spend time finding new information.

So I ask you to please list 'just one' source you consider to be
most important in keeping you well informed of goings on in
HiFi.

I look forward to reading some carefully considered replies.

Thanks

Stereophile, mainly Herb Reichert, and analog planet’s Michael Fremer...just a few...lots can be learned by just reading reviews, even on equipment you could never realistically afford...there is no one source really, you just have to continually seek the info you desire...the internet is a wonderful thing. I second the book suggested by MC...
You can look up different books online or you could consult someone online on the forums but reading a book will help more. 
Where ever you go you will run into bias. Since speakers are the most important item read The Loudspeaker Handbook (Second Edition) by John Eargle. 

Rule #1 Never listen to anyone who is trying to sell you something. This includes reviewers who are agents of the companies that advertise in their rag. Reviewers are generally not technical people, they are English majors. John Atkinson of Stereophile is an exception. 
Rule #2 Never listen to anyone who owns the equipment you are interested in. It will always be "great." 
Rule #3 Books are best. 

As for Audiogon the advice here is all over the map extending from excellent to mythological.
