In brief:
the WIIM Pros and BLUESOUND Nodes sound fine performing at their budget strata price point , (emphasis added on a fine but important distinction.)
BUT .,,, if you have a high-end audio system with its inherent far improved resolution capabilities, then you are missing out on a lot sticking with these budget class streamers
NOTE: if you do elect to upgrade your streamer, it is intuitively assumed that in most cases- you will also intuitively also move up too in lockstep to an upgraded DAC from the GESHELLI. Then the cables , et al. It’s the sum of the parts and not JUSTVan isolated piece alone, that forms the digital audio performance upgrade path down the Yellow Brick Road to Audio OZ.
