Dedicated devices that deliver high-resolution audio over Wi-Fi/Ethernet using protocols like DLNA, Roon Ready, or proprietary systems (e.g., Bluesound NADAC). Key features include support for 32-bit/384kHz PCM & DSD512, MQA full decoding, and multi-room synchronization. The Cambridge Audio CXN V2 exemplifies this category with its 32-bit/384kHz DAC and dual-band Wi-Fi.
