This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.\u003c\/li\u003e\n\u003cli\u003eIn music production, dynamic range means the difference between the loudest and quietest sounds. It’s measured in decibels, or dB for short.  In a single audio track, dynamic range means the dB difference between the loudest and quietest moment in the audio file. You can think of the dynamic range in a system as the space between the noise floor and the clipping point.  When a sound goes below the noise floor you won’t be able to tell the difference between the signal and the system noise of the medium.  When a sound goes above the clipping point, the tops of its waveform will get abruptly cut off, causing harshness and distortion. iFi’s proprietary technology extends the Dynamic Range by 6 dB or more, for an improved listening experience.\u003c\/li\u003e\n\u003cli\u003eiFi’s exclusive \u003cstrong\u003eS-Balanced® \u003c\/strong\u003ecircuit delivers maximum performance from single-ended and balanced headphones alike.\u003c\/li\u003e\n\u003cli\u003eTDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.
