It’s a phono amp built solely for moving magnet (MM) cartridges. By skipping moving coil support entirely, SMSL was able to simplify the circuit, lower the cost, and improve performance across the board. No relay switching. No compromise in headroom. Just a clean, solid phono stage built for a fraction of the cost of typical phono amps. Add a milled aluminum chassis, an integrated headphone amp, and a tuned 46dB gain stage, and you’ve got a true hi-fi component.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eMore volume, less compromise\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eMost phono amps hover around 38–40dB of gain. Not the PH-1. After testing MM cartridges ranging from budget-friendly to boutique, SMSL landed on a fixed 46dB gain—enough to bring your signal to around 1Vrms. This gives you a fuller, more dynamic signal that meets the demands of modern amplifiers without overdriving them.\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003eMM only—on purpose\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eNo switches. No MC circuit. The PH-1 is optimized exclusively for MM cartridges, which make up the overwhelming majority of what vinyl listeners use. By dropping MC support, SMSL was able to streamline the signal path and boost performance, achieving 50% better circuit metrics. \u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003eCompact, solid, and ready for real systems\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eThe PH-1 is carved from high-precision aluminum, giving it the mechanical strength and EMI resistance needed for analog playback. It’s compact—just 3.7 x 3.7 x 1.2” (94 x 96 x 30mm)—but still offers RCA jacks, USB power, a ground post, and a 6.35mm headphone output, all laid out with enough spacing to keep cable management painless. \u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003ePrivate listening, built in\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eSometimes you don’t want to fire up the speakers. That’s why the PH-1 includes a dedicated 6.35mm headphone amp with front-panel volume control. It also works great as a preamp for active speakers, giving you front-stage volume control without needing another box in the chain.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003eClean power, clean signal\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eThe PH-1 keeps noise out of the equation with an isolated dual power supply that rejects hum, buzz, and ground loop interference. Internally, the circuit layout is tight and deliberate, with short signal paths, low-noise op-amps, and gold-plated jacks all working together to preserve detail and minimize interference.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003eTwo years of tuning\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eThe PH-1 wasn’t rushed. Over 50 op-amps were tested. The board was revised more than five times. Dozens of MM cartridges were auditioned. The end result is a phono amp that sounds refined, getting the best out of a wide range of gear.\u003cbr\u003e\u003c\/p\u003e\n \u003ch3\u003e\n \u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eHigh-fidelity MM-only phono stage with 46dB gain\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eUltra-low THD+N: 0.008% (-81dB)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eIntegrated headphone amp with 6.35mm jack and volume control\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eHigh-precision CNC-machined chassis for EMI resistance\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eBuilt-in advanced power processing circuit with USB power input\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFixed 150pF input capacitance for easy compatibility\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eGold-plated RCA jacks for corrosion resistance and low signal loss\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eCompact 3.7 x 3.7 x 1.2 in (94 x 96 x 30 mm) form factor\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFront-panel ON\/OFF switch and volume knob\u003cbr\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\n \u003cstrong\u003eSpecs\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eHeadphone output power: 90mW x2 (32Ω)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eFrequency response: 20Hz–20kHz\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eTHD+N: 0.008% (-81dB, unweighted)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eChannel separation: -77dB @ 1kHz\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eGain: 46dB\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eSNR: 84dB\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003ePower consumption: 1W\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003ePower input: DC 5V 500mA\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDimensions: 3.7 x 1.2 x 3.7 in (94 x 30 x 96mm)\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eWeight: 0.45lbs (0.205kg)\u003cbr\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\n \u003cstrong\u003eWhat’s included\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eSMSL PH-1 MM Phono Amplifier\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eUSB power cable\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eUser manual\u003cbr\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e","brand":"SMSL","offers":[{"title":"Default Title","offer_id":46866222252207,"sku":"APS-1036-1","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/apos-audio-smsl-headphone-dac-amp-smsl-ph-1-mm-phono-amp-1169596516.png?v=1777716385","url":"https:\/\/freshized.com\/products\/smsl-ph-1-mm-phono-amp","provider":"Freshized","version":"1.0","type":"link"}
