{"product_id":"nuprimepra9xbl","title":"NuPrime PRA-9X Preamplifier with Phono, Black","description":"\u003cp\u003eThe NuPrime PRA-9X is a fully balanced stereo preamplifier with a MUSES8820 gain stage, integrated MM phono input and headphone output.\u003c\/p\u003e\u003cp\u003eIt is the control centre of an active chain: it takes in your sources, controls the level precisely and sends a clean signal to the power amplifier. Small in the case, big in the task – and with exactly the understated presence a good preamplifier should have.\u003c\/p\u003e\u003ch2\u003eWhy the PRA-9X?\u003c\/h2\u003e\u003cp\u003eA preamplifier decides how cleanly your signal reaches the power amplifier in the first place. For this, the PRA-9X relies on a digitally controlled volume control with analogue switches and internal chip resistors – no worn-out potentiometer that skews channels at the halfway position. The special thing: the control works in four channels with separate paths for L+, L−, R+ and R−, with a distortion of only 0.0004 %. Added to this is the fully balanced architecture with XLR input and output, so that even long cable runs to the power amplifiers stay noise-free. If you are building an active system, it makes sense to start here.\u003c\/p\u003e\u003cp\u003eNuPrime positions the 9X series for compact systems with a natural sound and fair value for money. Within it, the PRA-9X is the conductor: it delivers not a single watt itself, but has the final say over how loud it gets – and, with phono and headphone output, also over what actually gets played.\u003c\/p\u003e\u003ch2\u003eWhat you get\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e✅ \u003cstrong\u003eMUSES8820 with current-boost modules:\u003c\/strong\u003e According to NuPrime, the line outputs consist of MUSES8820 operational amplifiers with a current-boost circuit – high-quality components instead of off-the-shelf parts.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eFour-channel volume control:\u003c\/strong\u003e Separate paths for L+, L−, R+ and R−, in 0.5 dB steps with memory – ideal for mono power amplifiers 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 amplifier – the right choice for larger listening rooms.

Also ideal as a clean preamplifier in front of mono power blocks or actively controlled 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 pure analogue preamplifier – no DAC, no digital inputs. If you only get your music from a streamer or PC, you additionally need a DAC with an analogue output. The phono input is designed for MM cartridges; for an MC cartridge you need a step-up transformer or an external MC stage. And if you expect a touchscreen and app gimmicks, you will deliberately find only what is necessary here – but cleanly done.\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. It takes in sources, controls the level in four channels and passes the signal on fully balanced to the power amplifier – phono and headphone output are a genuine extra rather than a token jack. Together with an STA-9X or a pair of monoblocks, this makes a compact, active chain without a stack of boxes.\u003c\/p\u003e\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Fully balanced stereo preamplifier with MM phono and headphone output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamplifier stage:\u003c\/strong\u003e MUSES8820 gain stage, digitally controlled volume control with analogue switches and internal chip resistors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume control:\u003c\/strong\u003e Four-channel, separate paths L+, L−, R+, R−, 0.5 dB steps with memory\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain stage:\u003c\/strong\u003e MUSES8820 with current-boost modules\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 – equalisation:\u003c\/strong\u003e two-stage RIAA\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\u003ePreamplifier – input\/output impedance:\u003c\/strong\u003e 20 kΩ \/ 10 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamplifier – THD+N:\u003c\/strong\u003e 0.0004 % @ 7.5 V Vrms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreamplifier – signal-to-noise ratio:\u003c\/strong\u003e \u0026gt; 115 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone amplifier:\u003c\/strong\u003e 560 mW into 32 Ω \/ 110 mW into 600 Ω, THD+N 0.004 % (32 Ω, 480 mW), 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 90–130 VAC \/ 210–250 VAC (voltage selector switch); 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\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat's in the box:\u003c\/strong\u003e PRA-9X; further accessories on request\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDo I need a power amplifier for the NuPrime PRA-9X?\u003c\/strong\u003e\u003cbr\u003eYes. The PRA-9X is a pure preamplifier and only controls the level – the power comes from a separate power amplifier. A NuPrime STA-9X or a pair of monoblocks is a particularly good match. This is how you build a compact, high-resolution chain of matched components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I connect a turntable directly?\u003c\/strong\u003e\u003cbr\u003eYes, provided 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 additionally need a step-up transformer or an external MC preamplifier. We help you with the right setting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the PRA-9X have a DAC built in?\u003c\/strong\u003e\u003cbr\u003eNo. The PRA-9X is deliberately purely analogue. If you play digitally from a streamer, PC or CD player, you need a separate DAC with an analogue output, which you connect to one of the RCA or XLR inputs. We are happy to work out with you which DAC suits you sonically.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the headphone output of the PRA-9X any good?\u003c\/strong\u003e\u003cbr\u003eYes. According to NuPrime, the 6.3 mm output delivers 560 mW into 32 Ω and 110 mW into 600 Ω. For many listeners it replaces a separate headphone amplifier and makes the PRA-9X a complete vinyl and headphone hub.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy buy the NuPrime PRA-9X from HD Zürisee?\u003c\/strong\u003e\u003cbr\u003eBecause we build active chains every day and know which power amplifiers, speakers and sources suit the PRA-9X.
