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.
Does iFi Zen DAC need power?
ZEN DAC is powered by 5 volts, either via the enclosed USB cable (for connection to laptop or PC) or DC power supply (not included). Tip: For best performance upgrade the USB power supply to a super-low noise power adapter such as iFi iPower or iPower X. Note: For use with PC it is necessary to download drivers.
Is ZEN DAC also an amp?
