A great fit and good value.
The Nano is a perfect solution for a kitchen bookshelf setup where a Node was awkward in terms of size and to reach the controls on top. The Nano fits better in this space and is easier to use, while staying in the Bluesound family to sync with dining and living room players and access a Vault library. See pictures.
I hear no discernible difference between the Node (N130 - 2021) and the Nano, though the powered speakers in my kitchen aren't that revealing.
I've had four Node streamers for a few years and have never used the HDMI or USB functions on any of them, and only occasionally used the headphone jack on one of them. So the Nano is doing everything a Node has done for me in the past, but more affordably.
If you're just getting into streaming and this will be your first Bluesound player or you're expanding a Bluesound network, the Nano is great value.
I'm very happy with the Nano, especially at the Audio Factory price. This is the seventh Bluesound device I've bought form the Audio Factory. All run great and have collectively become the main source of music for several two-channel setups.
