Moving up from a Node 2i

Just did a test at a local dealer between the Vault 2 which is my current streamer and the Innuos Zenith mk3. The dealer set up a system consisting of DCS Bartok DAC, Gryphon integrated and Rockport Atria 2 speakers. There was a difference in signal path as the Vault was connected to the DAC via SPDIF and Zenith connected via USB. After listening to 3 well known tracks on the Zenith then switching over and listening to the same 3 tracks on the Vault, it was not hard to hear the difference. The Zenith is bigger with better defined / separated images in comparison to the Vault which sounds slightly muted in comparison. I also like Innuos's integration with Roon and being able to configure the Zenith as a core. Lastly, the potential to improve SQ down the road with their newly released Phoenix re-clocker (which I did not hear) is also interesting. I purchased the Zenith but you have to hand it to Bluesound, their price / performance is outstanding.

The Vault doesn't support wireless either. Initially I tried Ethernet over powerline but that was noisy. I then tried an inexpensive extender like big_greg and crn mentioned, but I experienced dropouts from time to  time. I finally installed Google mesh and that was the ticket for me. Very good performance throughout the house and it has a feature that allows you to prioritize your streamer if there is competing demand from others devices on the network.
