An AK4497S DAC stage, XU316 USB interface, native DSD512 support, LDAC Bluetooth, and balanced TRS\/RCA line outputs give you a desktop hub that slots neatly into a work desk or studio and raises the bar for what your music can do.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eCompact desktop hub for modern listening\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe E50 II is built for the desk first: small enough to sit under a monitor, solid enough to anchor a serious two-channel chain. With USB-C, coaxial, and optical digital inputs alongside balanced TRS and single-ended RCA line outputs, it connects cleanly to powered monitors, power amplifiers, and external headphone amps. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eAKM decoding with ultra-low distortion\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eAt its core is AKM’s AK4497S stereo DAC, part of the company’s updated VELVET SOUND family. The line-out stage delivers a THD+N of 0.0001% at 1kHz and up to 131dB of dynamic range, which means the DAC adds virtually no audible noise or distortion of its own. Quiet sections stay quiet, dense mixes stay open, and small details—reverb tails, room tone, fingers on strings—stay intact instead of smearing into the background.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFlagship USB platform with native DSD512\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eUSB duties are handled by the XMOS XU316 platform, giving the E50 II native support for DSD64–DSD512 and PCM from 44.1kHz up to 768kHz at 16–32 bit. A custom Thesycon USB driver on Windows and driverless operation on macOS keep the connection stable for both everyday streaming and critical listening. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFPGA clocking and ADAT-capable optical input\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eCoaxial and optical inputs run through an FPGA+PLL-based TopSync circuit with JitterNull processing to keep digital timing errors extremely low—down to about −160dB in common jitter tests. The optical input doubles as a dual-format S\/PDIF and ADAT port, so the E50 II can slot into more advanced studio-style workflows where multi-channel ADAT is part of the chain. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eLDAC wireless and Bluetooth flexibility\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003ePowered by the Qualcomm QCC5125 chipset, the E50 II adds a wireless side to your rig without throwing away fidelity. It supports LDAC, aptX Adaptive, aptX HD, aptX, AAC, and SBC codecs and can reach up to 96kHz \/ 24-bit over Bluetooth. That means you can keep a clean, wired link from DAC to speakers or amp while streaming directly from your phone or tablet, getting performance comparable to many dedicated digital audio players even when you are away from your desk.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eTen-band PEQ with app and desktop control\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eA built-in ten-band parametric EQ lets you tune your system rather than adapting to it. Through Topping’s self-developed algorithms and the Topping Tune software, you can adjust frequency, gain, and bandwidth per band, independently for left and right channels. The software supports importing target curves, compensating raw measurements, and saving multiple profiles for quick switching. Paired with the Topping Home app, you can manage EQ, volume, and routing from your phone without leaving your chair.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003ePowerful balanced and single-ended outputs\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe output stage is built to drive real-world gear. Single-ended RCA line out can be set to 2.6Vrms or 5.6Vrms, while the balanced TRS outputs reach up to 11.3Vrms (23.2dBu). Independent level options for single-ended and balanced outputs make it easier to match gain whether you are feeding an external headphone amp, a compact desktop power amp, or a pair of professional studio monitors, reducing the chances of overload or under-driving the next device in the chain.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eBuilt-in preamp mode with remote control\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eIn addition to fixed-level DAC mode, the E50 II offers a preamp mode where output volume is adjustable. That lets you run the DAC directly into a power amplifier or active monitors and control listening level from the E50 II itself. The included infrared remote adds another layer of convenience—mute, fine-tune volume, change inputs, and switch modes from the listening position instead of leaning over the desk every time.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFlexible TRS and RCA outputs\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eBoth balanced TRS and single-ended RCA outputs can be used independently or enabled at the same time. That makes it easy to feed two systems—like powered monitors and a separate headphone rack—or to keep one chain for work and another for relaxed listening. If you regularly move between speakers and an external amp, you can leave everything wired and simply change outputs rather than re-plugging cables.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eMinimalist interaction and clear display\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe front panel keeps things simple. Three brightness levels let you dial in the display for anything from dark-room listening to bright daytime use. Touch-sensitive controls handle the essentials with a tap, long press, or double tap—no extra knobs or switches fighting for attention. \u003c\/p\u003e\n \u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eCompact desktop DAC with AKM AK4497S chip for detailed, natural sound\u003c\/li\u003e\n \u003cli\u003eXMOS XU316 USB interface with native DSD512 and PCM up to 768kHz for lossless playback from modern sources\u003c\/li\u003e\n \u003cli\u003eBalanced TRS and single-ended RCA line outs with selectable output levels for clean matching to amps and monitors\u003c\/li\u003e\n \u003cli\u003eBuilt-in preamp mode with remote volume control so you can drive power amps or active speakers directly\u003c\/li\u003e\n \u003cli\u003eLDAC and aptX-family Bluetooth powered by Qualcomm QCC5125 for up to 96kHz \/ 24-bit wireless listening\u003c\/li\u003e\n \u003cli\u003eFPGA+PLL TopSync circuit and JitterNull technology for very low jitter and stable digital performance\u003c\/li\u003e\n \u003cli\u003eDual-format optical input that handles both S\/PDIF and ADAT for easy integration into studio and home rigs\u003c\/li\u003e\n \u003cli\u003eTen-band PEQ with independent left\/right profiles via TOPPING Tune and \u003ca href=\"#\"\u003eTOPPING Home app\u003c\/a\u003e control\u003c\/li\u003e\n \u003cli\u003eTouch-sensitive front panel, three-stage display brightness, and compact footprint that fits cleanly on a desk\u003c\/li\u003e\n \u003cli\u003eIncludes remote, dual USB cables, and Bluetooth antenna so you can start listening with minimal extra gear\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eProduct type: Desktop DAC with preamp mode\u003c\/li\u003e\n \u003cli\u003eDAC chip: AKM AK4497S stereo DAC\u003c\/li\u003e\n \u003cli\u003eUSB interface: XMOS XU316\u003c\/li\u003e\n \u003cli\u003eUSB sample rates: PCM 44.1kHz–768kHz \/ 16–32 bit\u003c\/li\u003e\n \u003cli\u003eUSB DSD support (Native): DSD64–DSD512\u003c\/li\u003e\n \u003cli\u003eUSB DSD support (DoP): DSD64–DSD256\u003c\/li\u003e\n \u003cli\u003eDigital inputs: USB-C, coaxial, optical (S\/PDIF \u0026amp;
