What do you read regularly to learn about audio products or research?

@melbguyone.........
I read all the same as you.  I miss HP as well. No one could write a review like him.  I met him once, he was very nice to me and not the pompous ass he was made out to be.  He was the main reason I got into the high end in the 70’s. 

@stereo5 You're a lucky guy. The Audiophile community misses him...

hifi engine.

+1 for the German "Stereo" . Only mag i trust as a buying guide .

Guys,

Thanks for the great tips. I can study the terms page and be ready for my first quiz in few days. (Ha)
What about an Audiophile Challenge? Post on a website a true/False list of say  50 important facts in the audio world and see who gets them right. 5 seconds to choose per question so no cheating encouraged.Top 10% move to the next level. $20 entry fee.  Somebody like Paul Gowan could be the moderator. I like it!!
