This, Stereophile's June 2023 issue, is the 50th I've produced as editor. That seems like a lotyet the four-plus years it took have flown by; it seems impossible that I've done this 50 times already. Still, the main thing it makes me think is how inexperienced I remain: It will take another 28 years to match JA1's record. That's unlikely to happen: I'm not sure when I'll retire, but I hope it will be before I turn 87. What have I learned? I've learned a lot about producing this magazine, and I've gained a lot of detailed knowledge, especially about specific hi-fi components.
