In terms of support, etc., Lumin is in a completely different league than Rose, but they’ve been on the market for much longer, and their approach is likely different than Rose’s.
However, when it comes to updates, both system and app-based, I wasn’t referring to the frequency, but rather to how they change and what they bring. For me, practically everything has been the same for many years, excluding, of course, the Connect, Roon, etc. features. For example, internet radio, while it was a disaster five years ago, remains so today. They haven’t improved anything in that regard, but overall, as I’ve written several times here, these are really great devices.
