With dual NOS\/OS modes, LDAC Bluetooth, and a precision 10-band PEQ, it gives you control over both the flavor and fidelity of your music. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFully differential 24-bit R2R DAC\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAt the heart of the K13 R2R are four channels of resistor arrays: 48 precision-thin film resistors per channel, 192 in total. Each resistor is matched to 0.1% accuracy with ultra-low temperature drift. The result is a true 24-bit fully differential R2R DAC that delivers a sound signature that’s rich, organic, and natural. Lower FFT harmonics mean darker backgrounds and less noise, so what you hear is only the music.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDouble the fun with Dual NOS\/OS modes\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eNOS (Non-Oversampling) Mode: Maintains the original sampling rate for decoding, preserving the authentic sound and allowing you to enjoy an organic and captivating musical experience.
