Built around a proprietary R2R + DSD architecture with true balanced 24-bit R2R and 6-bit DSD conversion, a 32-step FIR filter, and FPGA-based processing, it's made for clean switching between sources, balanced XLR output to your amp, and support for modern high-rate files over USB, including DSD1024 and PCM1536.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eProprietary r2r + dsd decoding\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eInstead of a typical delta-sigma DAC chip, the Czerny uses a discrete R2R path for PCM alongside a dedicated DSD approach. In plain English, it’s designed to convert digital to analog with tight control over accuracy and consistency, using hand-matched 0.01% resistors to keep channel balance and linearity as tight as possible. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eTrue balanced output you can actually use\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe Czerny is made for balanced gear. You get balanced XLR output for longer cable runs and better noise rejection in real rooms, plus single-ended RCA when you need it. Output levels are rated at 4.0Vrms on XLR and 2.0Vrms on RCA.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eLow noise, measurable performance\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eTotal harmonic distortion plus noise is listed at 0.004%, signal-to-noise ratio at 115dB, and dynamic range at 119dB. These numbers translate to a quiet background and clean headroom, especially noticeable late at night, low volume, and with resolving headphones or near-field monitors.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eClocking and buffering for cleaner timing\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eTiming errors show up as haze and softness. The Czerny leans on dual femtosecond crystal oscillators (45.1548MHz and 49.152MHz) and a FIFO buffer to steady the data stream before conversion, giving you more stable edges and image placement.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFPGA processing with oversampling or nos modes\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe signal processing is handled via FPGA, with selectable oversampling (OS) and non-oversampling (NOS). OS applies digital filtering and can sound tighter and more controlled depending on your chain. NOS skips that stage for a more direct path. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eInputs for all\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eUSB, coaxial, optical, and I²S are all here, so you can keep a streamer, CD transport, and computer in rotation without unplugging anything. USB is the high-rate path with support for DSD1024 and PCM1536. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003e65W toroidal transformer\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe internal power design starts with a 65W toroidal transformer and a bank of ERSE capacitors, then splits into 8 independently regulated supplies. That matters because digital, clocking, and analog output stages all want different kinds of power behavior. Keeping them isolated helps the output stage stay steady when the rest of the unit is working hard.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eCompact, rack-friendly sizing\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThis is a desktop-sized component that still feels like real hi-fi hardware. The overall dimensions are 9.45 in × 10.63 in × 2.36 in (240 mm × 270 mm × 60 mm), with a net weight of 13.78 lb (6.25 kg). It fits easily on a credenza, under a monitor stand, or in a rack shelf where height is tight.\u003c\/p\u003e\n \u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eProprietary R2R + DSD architecture\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eTrue balanced 24-bit R2R + 6-bit DSD conversion\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003e32-step FIR filter\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFPGA digital signal processing\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eOversampling (OS) and non-oversampling (NOS) modes\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDual femtosecond crystal oscillators: 45.1548MHz, 49.152MHz\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFIFO buffer and low-noise power supply\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eUSB supports DSD1024 and PCM1536 (listed)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDigital inputs: USB, coaxial, optical (TOSLink), I²S\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eAnalog outputs: balanced XLR and single-ended RCA\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eWindows Thesycon USB driver support\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eNo driver required for Mac and Linux (listed)\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: Digital decoder (DAC)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eMaterial: Aluminum alloy\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eColor: Black\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDimensions: 9.45 in × 10.63 in × 2.36 in (240 mm × 270 mm × 60 mm)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003ePackage dimensions: 17.72 in × 14.96 in × 6.30 in (450 mm × 380 mm × 160 mm)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eNet weight: 13.78 lb (6.25 kg)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eGross weight: 21.39 lb (9.7 kg)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eAnalog outputs: RCA 2.0Vrms, 625Ω\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eAnalog outputs: XLR 4.0Vrms, 1250Ω\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFrequency response: 20–70kHz (-3dB)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eTHD+N: 0.004%\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eSNR: 115dB\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDynamic range: 119dB\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eStereo crosstalk: -124dB\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDSD support: All inputs support DSD64-DoP; USB input only supports DSD1024 (listed)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003ePCM support: 24-bit \/ 44.1, 48, 88.2, 96, 176.4, 192kHz on all inputs (listed)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eUSB PCM support: up to 1536kHz (listed)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDigital inputs: Coaxial ×1, Optical ×1, I²S ×1, USB 2.0 Type B\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003ePower requirements: 100–240VAC, 50\/60Hz (manual selection listed)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003ePower consumption: ≤20W\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFuse: T2A\/250VAC, 5×20mm, 2A slow-blow\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eOperating temperature: 14°F to 104°F (-10°C to 40°C)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eRelative humidity: ≤90%\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eAtmospheric pressure: 86 to 106kPa\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\u003cstrong\u003eWhat’s included\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eCzerny digital decoder\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003cp\u003e \u003c\/p\u003e","brand":"LADDER","offers":[{"title":"Default Title","offer_id":46866188304559,"sku":"APS-1223-1","price":829.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/apos-audio-ladder-headphone-amp-ladder-czerny-r2r-desktop-dac-1214393161.png?v=1777716153","url":"https:\/\/freshized.com\/products\/ladder-czerny-r2r-desktop-dac","provider":"Freshized","version":"1.0","type":"link"}
