I mean, depends on pricing. Sub $1500 like they usually go for and its a great player. Maybe there are better sq/$ deals if you get something like an opus #2, but those players very much so feel crazy old and the sp1000 just doesn't. Plus, tbh, it goes well with most stuff. Clears, Arya, mest, VX, diana V2, and basicaky everything I own works well on the sp1k. Are there better portable pairing for each? Yes. Are those better pairing availible under 1.5x what a sp1000 goes for used? No, they tend to be in the 3-4k usd + range.
TLDR - not worth at retail, very worth at used pricing
Edit: good point about apps, but keep in mind android 5 to Android 6 was a massive massive change. Once Android 6 is not supported you will proabaly need Android 8+. Plus, tbh, roon just works and is better than the tibal app anyways
