I just put together that Tyll Herstens had retired and wasn't just writing less. : ( The reason I'm posting to this (quite old) thread, is because I think it's important to tell people when they affect our lives positively. I avidly read Tyll's reviews back in 2012-15 when I got back into the audio hobby after a long break. I appreciated his writing so much because it was colorful, approachable, and yet technical enough to truly inform -- the kind of writing one does when one really understands a discipline and is secure in one's knowledge. I never felt excluded or talked down to, but rather, encouraged to dive in and enjoy music, whether my budget was $100 or $10,000. His explanations of frequency graphs made sense and helped me to understand how good audio can be demonstrated visually (even if it's not the whole story). His recommendations pushed me to buy the Shure se215, Sennheiser Amperior, and a couple of other lower-end headphones that I did not once regret buying. Just last month, his recommendations helped me to pull the trigger on the MassDrop 6XX, which I am enjoying immensely. These days, headphone reviews are much more plentiful online (more quantity than quality in some cases) than they were in 2012, but I still feel they chase after the example Tyll set. I'm sorry to learn he needed to hang it up, but am grateful for the columns and insight, which I still refer to. Tyll, sir, I hope you're having a fantastic time on the road! Thanks for your good work.
