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

I would love to hear from several well-seasoned members what publications, blogs or newsletters
they subscribe to or read when they can? I am trying to learn how to learn about today's audio world
from as straightforward and unbiased sources as possible.
Thank you.
I do the rounds of the major review sites incl: Soundstage Network (in particular Soundstage Ultra), TAS, Positive Feedback, 6 Moons, Stereophile, Hifi+, Hifi Critic, Part Time Audiophile, Mono & Stereo (via FB) and check out the free Tone Publications & German Stereo magazine editions each month. In addition, I follow several reviewers & prominent Dealers on FB (too many to mention).

Other members i’m sure will also chime in with their thoughts, though in my 30 years in this hobby, I’ve found those sites to be reliable sources of reviews, articles and new equipment announcements. It’s just a shame that great writers like Harry Pearson are no longer with us.

Another useful resource to assist with learning audiohile terms is the Stereophile Audio Glossary - https://www.stereophile.com/reference/50/index.html Hope that helps!
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...
+1 for the German "Stereo" . Only mag i trust as a buying guide .

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!! 
I forgot to mention High Fidelity magazine. Wojciech Pacuła is one of the best reviewers out there imho.
Audiophile Magazine. Excellent reviews!
Publications: TAS, Stereophile, HiFi +, HiFi News & Record Review.
Blog: dailyaudiophile.com
Happy Listening!
+1 on dailyaudiophile.com as they have links to 90 review and test sites.
I don't read any of that crap. Well, hardly. Anymore.

Of course I had subs before the interwebs but those days are long gone. Now I still sometimes read reviews but what you really want to know is:
 how to learn about today's audio world
Which is a different question altogether.

Top of the list, get and read and study like your life, well wallet anyway, depends on it: Robert Harley, The Complete Guide to High End Audio.

Its not perfect but read it and you will understand exactly what all the components do, and why, and even how. Even better, you will learn the importance of listening, and even more important than that how to listen, what to listen for, and best of all an essential glossary of audiophile terms like grain and glare, attack and decay, on and on. 

I love the way you say "learn how to learn" because that for sure is the key. Its not enough for example to read reviews. You need to learn how to read reviews. This like everything else it seems is a multi-step process. Read to learn the terminology. Read to understand where the reviewers are coming from. Fremer for example loves a hyper-detailed fast sound. Also to stick with Fremer he is the champ he is because he works hard to make sure you know where he is coming from. Not many do. Then the essential next step, you actually go and listen and hear for yourself what the stuff they write about sounds like. 

Three most important words in audiophiledom: go and listen.

Its not easy. You are now in a field where to be really good at it you have to learn to master a whole bunch of technical mumbo-jumbo, which you only realize is indeed mumbo-jumbo after you have mastered it. Then you have to listen for a slew of technically valid audio traits- tone, dynamics, imaging- that in turn must be thrown right out the window. Because you simply cannot enjoy music while listening for technical factors like that. We even have a term for this, audiophilia nervosa, the inability to relax and enjoy the music because you can't stop thinking analytically about how it sounds. So you have to do what ruins the music in order to build something that delivers the music so well that it carries you away and frees you from all this technical mumbo-jumbo.

It ain't easy.

Good luck!
