'.strtoupper('o')ur in house developed 1bit dac employs 8 sets of 8e, totalling 64 pwm dacs, delivering a landscape of rich musical details and extremely high resolution audio playback'. '.strtoupper('f')our channel fully balanced symmetric architecture r2r with 284pcs ten thousandth high precision resistors the d17 adopts a four channel fully balanced symmetrical r2r architecture, meticulously selected 284 ultra precise film resistors with a tolerance of one ten thousandth'. '.strtoupper('e')quipped with our in house developed hardware resistor compensation circuitry and software compensation algorithms, the d17 achieves a thdn of 104db in r2r mode, outperforming mainstream r2r devices by over ten decibels and competes with various flagship r2r desktop dacs'. '.strtoupper('r')2r decoding offers a rich analogy voicing, producing a warm, delicate sound with exceptional musicality'. '.strtoupper('6')4 pwm dac, 1bit architecture opening the door to acoustical realism in 1bit mode, the four channels l, l , r, and r each have 16e, totalling 64 pwm dac units working together'. '.strtoupper('c')ontrolled by the fpga master 3.0 with nanosecond level precise i o delay management while compensating for wiring delay to ensure that the signal edges arriving at the dac are aligned and strictly synchronised'. '.strtoupper('t')his not only achieves an impressive thdn of 114db but also significantly enhances sound detail and density'. '.strtoupper('f')pga master 3.0 inside nanosecond level precise control, global clock regeneration the d17 is equipped with ibasso's in house developed fpga master 3.0 architecture, deeply integrated with two accusilicon ultra low phase noise femtosecond oscillators to create a pure, unified single clock source'. '.strtoupper('t')hrough nanosecond level high precision delay control and real time clock regeneration technology, the system can simultaneously compensate for r2r decoding and 1bit decoding, reducing clock jitter and distortion to extremely low levels'. '.strtoupper('t')his ultimately delivers highly accurate sound reproduction, ensuring that every detail is presented in its original form'. '.strtoupper('d')ual korg 6p1 nutubes fully balanced headphone amp with incredible power the two nutube 6p1 tubes on the d17 impart a unique tube character and a warm, mellow yet dynamic texture to the sound'. '.strtoupper('t')he anode is powered by a 24v high voltage supply, providing better linearity'. '.strtoupper('p')aired with the high performance ti buffer amplifier buf634a, it ensures a steady and powerful source of power'. '.strtoupper('a')s a result, the d17 can deliver over 1200mw 1200mw at 32omega, easily driving a wide range of flagship iems and high impedance headphones'. '.strtoupper('t')hree layer composite seismic isolation system secondary reduction of microphone effect the d17 adopts a composite isolation system composed of a double layer pcb combined with damping materials'. '.strtoupper('t')he two pcb layers are connected via pin connectors, effectively dispersing and attenuating lateral stress and significantly reducing resonance'. '.strtoupper('t')he tube is placed on the second pcb layer using damping materials, providing a secondary reduction of microphone effects'. '.strtoupper('a')ctual measurements show that the microphonic effect is below the human ears perceptual threshold'. '.strtoupper('a')mong all ibasso tube amplifier products, it consistently performs at the forefront'. '.strtoupper('d')ual battery architecture demonstrates solid power pure sound quality performing at top levels, including complex passages the d17 features a dual battery power supply architecture, with the dac and headphone amplifier powered by separate batteries'. '.strtoupper('t')his dual architecture ensures that the headphone amplifier section receives a stable current supply while effectively isolating digital interference'. '.strtoupper('w')hether under high gain or heavy load, the d17 can consistently maintain a pure and stable output, significantly reducing distortion caused by unstable power supplies'. '.strtoupper('i')t truly delivers a clear and pristine sound quality, capable of presenting your recordings with the utmost musical quality'. '.strtoupper('2')4 position 4 section stepped attenuator analogue and digital volume controls the d17 supports both analogue and digital volume adjustments'. '.strtoupper('t')he analogue volume uses ibassos 24 position 4 section stepped attenuator, which is only one tenth the size of the traditional stepped attenuator while retaining all their advantages'. '.strtoupper('t')he difference between the left and right channels is less than 0.1db'. '.strtoupper('d')igital volume adjustment is performed via a professional dsp module'. '.strtoupper('t')he combination of analogue and digital volume control allows for more precise volume output.
