Many companies in high-end audio and elsewhere use a trickle-down approach to advance their products. The process begins with the development of a suite of new technologies, capabilities, components, or whatever the relevant entities might be. Typically, it's a flagship product that functions as the impetus, target, and first deployment of the new technologies. Subsequently, the new technologies trickle down to other models, each one incorporating a subset appropriate to its price point.

I was planning one of my occasional long drives, for music and photography. I had scheduled two nights in Nashville, so I asked around: Where should I go for live music after a dinner of Hattie B's hot chicken? Art Dudley recommended the Station Inn, perhaps the world's best venue for live bluegrass music. You can read about my experience there in the November 2019 Stereophile. The Station Inn has now added a streaming service. For $8.99/month or $99/year, you get between 10 and 20 live-streamed performances every month plus access to the archives. If you're a bluegrass fan or merely bluegrass-curious, I encourage you to check it out. It's not as good as being there, but it's still good.
