A custom silver-plated 6N copper umbilical cable joins the two chassis, the rigid, damped cases isolate vibration and help heat escape, and a 60-second soft start lets the tubes warm up and settle before the sound comes on.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-ha-6a-mk2-kt88-tube-amplifier-with-external-psu-photo-psu2.jpg?v=1791383248\" alt=\"Outboard power supply of the Cayin HA-6A MK2\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-ha-6a-mk2-kt88-tube-amplifier-with-external-psu-photo-psu.jpg?v=1791381765\" alt=\"Power connection between the two chassis of the Cayin HA-6A MK2\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eBuilt by hand with in-house transformers\u003c\/h3\u003e\n\u003cp\u003eCayin makes its own transformers: a custom toroidal power transformer with high-purity copper windings for low magnetic noise, in a shielded, encapsulated housing with extra circuit protection, and wide-bandwidth EI output transformers for minimal signal loss.

Headphones connect by 6.35mm, 4.4mm or 4-pin XLR. The 4-pin XLR is the full-power balanced output; the 4.4mm output is deliberately quieter, with a better signal-to-noise ratio for sensitive headphones and IEMs, and can also help if a system picks up hum. Matching the impedance gives a natural sound with well-defined bass; planar headphones are especially sensitive to it, so try the settings once you know the sound. A higher setting gives more output power, because it drives a harder load, unlike a solid-state gain switch.

The ES9038PRO’s output current is strikingly high, especially with its channels paralleled to average out errors, so most designs use a separate I\/V converter for each DAC channel and combine them afterwards, which adds errors from the tolerance of each converter’s resistor. In WANDLA, Ferrum parallels the ES9038PRO’s outputs directly and converts the combined current in a single composite amplifier: a fast, low-noise current-feedback op-amp, which keeps the input impedance low even at the very high frequencies of the DAC’s delta-sigma signal, paired with a fast high-current buffer. With the same op-amp, the conventional four-converter layout measured over 10dB more distortion.

ERCO now decodes 768kHz PCM and DSD512, intermodulation and intersample distortion are reduced, and output levels meet current standards.

with the K17’s 4,000mW discrete amplifier, and dresses it in metal and real wood. In FiiO’s words, the warm touch of natural wood speaks to the eyes and hands, while the rich, full-bodied R2R sound brings the warmth of analogue back to your ears.

In this segmented design, the upper five bits are decoded by 31 thermometer-coded resistors, which avoids the error build-up of a traditional R2R ladder and reduces distortion. FiiO’s self-developed, new-generation FPGA architecture feeds PCM and DSD to the array, with a choice of OS (oversampling) or NOS (non-oversampling) modes. The result is the sound people love R2R for: clear yet smooth, natural, warm and endlessly listenable.\u003c\/p\u003e\n\u003cp\u003eThree low phase noise femtosecond oscillators, two ACCUSILICON AS318-L (45.1584MHz and 49.1520MHz) and a FiiO-customised 12MHz part, greatly reduce the effect of phase noise, so every sample rate is restored precisely for a purer, more consistent sound.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-k17-r2r-desktop-dac-and-headphone-amplifier-photo-clocks.jpg?v=1791340430\" alt=\"The three femtosecond oscillators of the FiiO K17 R2R\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eFully balanced, with a discrete 4,000mW amplifier\u003c\/h3\u003e\n\u003cp\u003eThe whole circuit is fully differential, from the DAC through I\/V conversion and low-pass filtering to the headphone amplifier, for high dynamic range and much lower crosstalk.

The headphone amplifier is a carefully crafted, fully discrete op-amp plus transistor current-amplification design, built around the classic ON Semiconductor MJE243\/253 pair: it delivers high current with low output impedance, for up to 4,000mW + 4,000mW from the balanced outputs, nearly double the K9 Pro ESS, easily driving all kinds of headphones and IEMs with a smooth, pleasant and natural sound.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-k17-r2r-desktop-dac-and-headphone-amplifier-photo-amp.jpg?v=1791340434\" alt=\"The discrete 4,000mW headphone amplifier of the FiiO K17 R2R\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA 64-bit DSP for a 31-band lossless PEQ and Auto EQ\u003c\/h3\u003e\n\u003cp\u003eAn M21586Q DSP (double-precision 64-bit floating point at 360MHz), an ES9821Q ADC and a custom femtosecond oscillator let you use the 31-band high-precision lossless PEQ in every mode, analogue inputs included, and provide robust output protection.
