Buying Guide – How to Choose the Best DAC for Kz Castor
Selecting the right DAC involves considering compatibility power and build. This section outlines the key factors to help you decide on the perfect match for your Kz Castor IEMs.
Output Power
Ensure the DAC provides enough power to drive your IEMs. High sensitivity units work well with low power but strong drivers need robust amps.
