Not all Bluetooth is created equal !
Have utter confidence in the sound quality of the ZEN Blue. It uses Bluetooth5.0, the very latest version, and the newest Qualcomm 5100 chip to process all incoming Bluetooth data. There ESS Sabre DAC chip is there to ensure an extremely smooth digital to analogue conversion. Banish standard ‘Bluetooth Blues’ with the iFi hi-res implementation.
Analogue – connect via RCA to amps or active speakers or via the 4.4mm output to amps/speakers with a balanced input.
Digital – use the optical and coaxial connections to connect to anything with a built-in DAC and corresponding digital input; your TV, an AV amp or an external DAC in your hi-fi set-up.
