I'm glad to see a reputable American company introduce something like this. Many good loudspeakers and amps are made in USA, but when it comes to streamers (or streaming DACs/preamps), most of the best products seem to be Asian, European, or Canadian. Streamers and DACs are prone to software/firmware problems. This makes after-sale service/support important. For American customers, I believe this is best provided by an American company (or by a foreign company with a strong North American presence.).
The AirLens product itself does not excite me much. I'd rather have streaming functions integrated with the DAC/preamp in a single box (like PS Audio's old Direct Stream Junior, without any kinks in the ethernet "bridge"). With a dedicated streamer, maybe half of what you'll pay for is the fancy case and connections. More clutter, more complexity, and more cost, probably with little or no sound improvement compared to putting an ethernet port on the back of a high quality DAC/preamp. But if PS Audio provides a really good app to control it, and if it's Roon-ready with good integration into the rest of your system, then it might be worth considering if all you're missing is a streamer.
