{"product_id":"kecessphono","title":"KECES SPhono Phono Preamp with Power Supply","description":"\u003cp\u003eThe KECES SPhono is a phono preamp built in a dual-mono design that accepts two MM and two MC cartridges and is powered by a separate 48-volt power supply.\u003c\/p\u003e\u003cp\u003eIt's aimed at anyone running more than one turntable or more than one tonearm – and at anyone who doesn't want to crawl behind the rack every time they swap cartridges. You control switching, gain and loading from the front.\u003c\/p\u003e\u003ch2\u003eWhy the KECES SPhono?\u003c\/h2\u003e\u003cp\u003eBecause a phono stage has to do two things at once: be extremely quiet and extremely flexible. The SPhono solves that with a consistently dual-channel-separated design and an outboard power supply that keeps the sensitive amplifier section away from the transformer. Four inputs, six selectable MC loadings, six capacitance values for MM and two equalisation curves cover practically any cartridge you'll come across.\u003c\/p\u003e\u003ch2\u003eWhat you hear\u003c\/h2\u003e\u003cp\u003eQuiet between the grooves. The RIAA equalisation stays accurate to within 0.2 dB of the original, the subsonic filter removes record warp and tonearm resonance from the deep bass, and the balanced XLR output carries the signal cleanly to the preamp even over longer runs. If you collect pre-1955 pressings, switch to the IEC curve and hear the recording the way it was cut.\u003c\/p\u003e\u003ch3\u003eWho is the SPhono for – and who isn't it for?\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eStraight talk:\u003c\/strong\u003e if you run one turntable with one MM cartridge and want to stay that way, you don't need this much – a smaller stage will do the job. The SPhono is worth it if you run several cartridges in parallel, use high-quality MC pickups, or genuinely care about loading resistance. And it needs space: two housings, 8.5 kilos together.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eA grown-up phono stage for people who take vinyl seriously and want to switch cartridges without improvising. At HD Zürisee in Wädenswil, we'll go through which loading suits your cartridge – that's the setting most of the music hangs on.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: phono preamplifier, dual-mono design, with separate power supply\u003c\/li\u003e\n\u003cli\u003eInputs: 2× MM, 2× MC, switching on the front\u003c\/li\u003e\n\u003cli\u003eGain MM: 40 dB \/ 46 dB\u003c\/li\u003e\n\u003cli\u003eGain MC: 60 dB \/ 66 dB\u003c\/li\u003e\n\u003cli\u003eMC loading resistance: 56 \/ 100 \/ 220 \/ 470 \/ 1200 \/ 47000 ohms\u003c\/li\u003e\n\u003cli\u003eMM input capacitance: 47 \/ 100 \/ 150 \/ 220 \/ 330 \/ 470 pF\u003c\/li\u003e\n\u003cli\u003eEqualisation: RIAA and IEC, accuracy 0.2 dB\u003c\/li\u003e\n\u003cli\u003eSubsonic filter: switchable on the front\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz – 20 kHz\u003c\/li\u003e\n\u003cli\u003eTHD: MM below 0.002%, MC below 0.09%\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio: MM 96 dB (A-weighted), MC 82 dB (A-weighted)\u003c\/li\u003e\n\u003cli\u003eOutputs: XLR balanced, gold-plated RCA\u003c\/li\u003e\n\u003cli\u003ePower supply: external SPhono power supply, ±48 V and +15 V, 18 W\u003c\/li\u003e\n\u003cli\u003eHousing: aluminium, 4 mm wall thickness (both units)\u003c\/li\u003e\n\u003cli\u003eDimensions per unit (W×D×H): 300 × 220 × 66 mm\u003c\/li\u003e\n\u003cli\u003eWeight: preamp 3.5 kg, power supply 5 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eCan I connect two turntables at the same time?\u003c\/h3\u003e\u003cp\u003eYes, and even more: the SPhono has four inputs – two for MM and two for MC cartridges. You switch between them from the front. For two decks, or one turntable with two tonearms, that's exactly the right solution.\u003c\/p\u003e\u003ch3\u003eWhich loading resistance does my MC cartridge need?\u003c\/h3\u003e\u003cp\u003eThat's usually stated in your cartridge's datasheet; a common rule of thumb is ten times the internal impedance. The SPhono offers six steps from 56 to 47,000 ohms. Tell us your cartridge and we'll give you the right starting value.\u003c\/p\u003e\u003ch3\u003eWhat's the IEC curve good for?\u003c\/h3\u003e\u003cp\u003eHistorical pressings. Records from before the RIAA standard were equalised differently; the IEC setting approximates that cut. With modern records, stick with RIAA – the difference is clearly audible, but only welcome on the right discs.\u003c\/p\u003e\u003ch3\u003eWhy an external power supply?\u003c\/h3\u003e\u003cp\u003eBecause the transformer is the loudest component in a phono stage, and the signals here are among the smallest in the whole system. Physically separate housings keep stray fields away from the sensitive input – with MC cartridges at 66 dB of gain, every microvolt counts.\u003c\/p\u003e\u003ch3\u003eWhy buy the KECES SPhono at HD Zürisee?\u003c\/h3\u003e\u003cp\u003eBecause a phono stage without the right settings is only half the job done.
