The N10 is a very good streamer. There have been sound quality improvements in the next generation. Some folks have said the N200 and N10 sound very similar. But the N10 is a fully fleshed out streamer. I would buy the N10. Then in ten years or so if you get the urge you can upgrade it.
I own an N100 for my headphone system and a W20SE (Aurrender’s flagship) and have had heard the N10. I would go N10.
