What DAC chip is in the iFi 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.
Is iFi Zen can worth it?
I own both units, and my answer is a resounding yes. I compared the balanced headphone out on both units with headphones and IEMs. Even with IEMs, there are significant improvements in terms of soundstage, precision, resolution, separation, and bass control with the ZEN CAN versus the ZEN DAC.
Can ZEN DAC connect to Zen Blue?
The DAC and the Blue are digital to analog converters. However, it’s not possible to use the Blue as a DAC and the DAC as a pre-amp before the Can (Zen DAC has outputs but not inputs), you only can use it as a source. So, the three brothers can’t all be used together at the same time.
