DMS-650 versus DMS-700
Two mid-range DMS players: the primary documented advancement is the AK4499EQ chip and the conversion architecture.
The DMS-650 replaces the DMS-550 as the entry point to the platform; the DMS-700 occupies the intermediate tier with AK4499EQ and true balanced output.
Both feature Wi-Fi ac, MQA, and the shared DMS user guide with the DMS-800 PV.
Cary Audio states a dynamic range of 121 dB for the DMS-650 and 124 dB for the DMS-700.
