{"product_id":"nuprimepra9xsi","title":"NuPrime PRA-9X Preamplifier with Phono, Silver","description":"\u003cp\u003eThe NuPrime PRA-9X is a fully balanced stereo preamplifier with a discrete Class-A output stage, an integrated MM phono input, and a proper headphone amp.\u003c\/p\u003e\u003cp\u003eIt's the switchboard of an active chain: it takes in your sources, controls the level losslessly, and sends a clean signal to the power amp. Small in the chassis, big in the job – with exactly the understated presence a good preamp should have.\u003c\/p\u003e\u003ch2\u003eWhy the PRA-9X?\u003c\/h2\u003e\u003cp\u003eA preamp decides how cleanly your signal even reaches the power amp in the first place. The PRA-9X relies on a discrete Class-A circuit and a lossless, FPGA-based volume control – no worn-out potentiometer that skews the channels at half setting. On top comes a fully balanced architecture with XLR input and output, so long cable runs to the power amps stay noise-free too. If you're building active, this is sensibly where you start.\u003c\/p\u003e\u003ch2\u003eWhat you get\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e✅ \u003cstrong\u003eDiscrete Class-A preamp:\u003c\/strong\u003e High resolution of detail and an organic, natural tonal foundation – especially with voices and acoustic music.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eLossless FPGA volume:\u003c\/strong\u003e Precise levels with no loss of sound quality across the whole range, ideal for mono power amps or active speakers.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eFully balanced:\u003c\/strong\u003e XLR input and output for low-noise, long connections to the power amp – the right choice for larger listening rooms.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eIntegrated MM phono:\u003c\/strong\u003e Input resistance and capacitance selectable in steps, so your MM cartridge is matched exactly.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eClass-A headphone output:\u003c\/strong\u003e 560 mW into 32 Ω with control and current even for demanding studio headphones.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eTrigger on\/off:\u003c\/strong\u003e Switches power amp and sources on in sync – tidy operation with no socket acrobatics.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eVideo\u003c\/h2\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;max-width:100%;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/61xOKn8vvH4\" title=\"NuPrime Audio 9 series\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/div\u003e\u003ch3\u003eWho is the PRA-9X for?\u003c\/h3\u003e\u003cp\u003eFor anyone building an active system: PRA-9X plus one or two NuPrime power amps make a compact, high-resolution chain without a stack of boxes. Also ideal as a clean preamp ahead of mono end blocks or actively driven speakers – and as an honest phono and headphone hub for vinyl listeners.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStraight talk:\u003c\/strong\u003e The PRA-9X is a purely analogue preamp – no DAC, no digital inputs. If you only pull your music from a streamer or PC, you'll need a DAC with an analogue output as well. The phono input is designed for MM cartridges; for an MC cartridge you'll need a step-up transformer or an external MC stage. And if you're expecting a touchscreen and app frills, you'll find deliberately just the essentials here – but done cleanly.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eWe recommend the PRA-9X to anyone who wants to build a serious active chain in little space. In Wädenswil we appreciate how quietly and neutrally it passes on the signal – the FPGA volume keeps sound purity intact even at low levels, and the Class-A headphone output is a genuine extra rather than an alibi jack. Paired with an STA-9X or a pair of monoblocks, this combination makes considerably pricier towers look old.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Fully balanced stereo preamplifier with MM phono and headphone amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamp stage:\u003c\/strong\u003e Discrete Class-A, FPGA-based lossless volume control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 1 × phono MM, 2 × analogue stereo RCA, 1 × analogue stereo XLR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1 × stereo RCA, 1 × stereo XLR, 1 × headphone 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhono MM – resistance:\u003c\/strong\u003e 32 kΩ \/ 47 kΩ \/ 100 kΩ (selectable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhono MM – capacitance:\u003c\/strong\u003e 100 pF \/ 220 pF \/ 320 pF (selectable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhono MM – sensitivity\/gain:\u003c\/strong\u003e 4.0 mV @ 1 kHz \/ 50 dB @ 1 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamp – input\/output impedance:\u003c\/strong\u003e 20 kΩ \/ 10 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamp – THD+N:\u003c\/strong\u003e 0.0004 % @ 7.5 V Vrms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamp – signal-to-noise ratio:\u003c\/strong\u003e \u0026gt; 115 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone amp:\u003c\/strong\u003e Class-A, 560 mW into 32 Ω, THD+N 0.004 %, dynamic range \u0026gt; 115 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 0 Hz – 50 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem control:\u003c\/strong\u003e Trigger input and output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower supply:\u003c\/strong\u003e Worldwide AC voltage; slow-blow fuse T1A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W × H × D):\u003c\/strong\u003e 235 × 55 × 281 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis:\u003c\/strong\u003e Aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e PRA-9X, infrared remote, power cable, quick guide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDo I need a power amp for the NuPrime PRA-9X?\u003c\/strong\u003e\u003cbr\u003eYes. The PRA-9X is a pure preamp and only controls level – the power comes from a separate power amp. An NuPrime STA-9X or a pair of monoblocks are a particularly good match. That way you build a compact, high-resolution chain of well-matched components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I connect a turntable directly?\u003c\/strong\u003e\u003cbr\u003eYes, as long as your cartridge is an MM type. The integrated phono input can be adjusted in resistance (32\/47\/100 kΩ) and capacitance (100\/220\/320 pF). For an MC cartridge you'll also need a step-up transformer or an external MC preamp. We'll help you find the right setting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the PRA-9X have a built-in DAC?\u003c\/strong\u003e\u003cbr\u003eNo. The PRA-9X is deliberately built purely analogue. If you play from a streamer, PC, or CD player digitally, you'll need a separate DAC with an analogue output, connected to one of the RCA or XLR inputs. We're happy to help you find the DAC that suits your sound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the PRA-9X's headphone output any good?\u003c\/strong\u003e\u003cbr\u003eYes, the output works in Class-A technology and delivers 560 mW into 32 Ω. That's enough for control and dynamics even with critical studio headphones. For many listeners it replaces a separate headphone amp and turns the PRA-9X into a complete vinyl and headphone hub.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy buy the NuPrime PRA-9X at HD Zürisee?\u003c\/strong\u003e\u003cbr\u003eBecause we build active chains every day and know which power amps, speakers, and sources suit the PRA-9X.
