With precision tuning and advanced circuitry, it brings out the best in your MM cartridge setup.\n\n\n\n\nGolden Gain, Super Energy\nWhile most entry-level MM phono amps offer only 38–40dB gain, PH-1 delivers a fixed 46dB gain. This results in approximately 1Vrms output—perfect for modern amplifiers, with fuller dynamics and denser sound, all without overloading the next stage.\n\n\n\n\nExclusive MM Design, Ultra-Low Distortion\nPH-1 is exclusively designed for MM cartridges, unlike many models with MM/MC switching. This dedicated design removes unnecessary MC circuitry, improving circuit performance by 50%, enhancing user convenience, and keeping costs low while maintaining top-tier sound quality.\n\n\n\n\nCNC Compact Machining\nThe high-precision CNC-machined chassis ensures mechanical stability and excellent EMI resistance. Whether in complex electromagnetic environments or daily use, PH-1 delivers stable, pure performance.\n\n\n\n\nReliable \"Quantification\" for Vinyl Playback\nFor vinyl enthusiasts, PH-1 also serves as a reliable reference tool. It helps identify playback issues and pairs well with step-up transformers, allowing the use of MC cartridges through external SUTs with weak amplification but great sound.\n\n\n\n\nPalm-Sized but Fully Featured\nMeasuring just 94×30×96mm, PH-1 offers six full-size connectors (power, L/R input, L/R output, GND) while maintaining a spacious layout. Its compact form factor allows for easy placement without compromising usability.\n\n\n\n\nIntegrated Headphone Amplifier\nPH-1 features a built-in high-quality headphone amp with a front-panel 6.35mm jack. Ideal for scenarios where speakers are inconvenient, it can also act as a preamp volume controller for active speakers.\n\n\n\n\nAdvanced Isolated Power Supply\nWith a dual isolated power supply design and external DC input, PH-1 eliminates common A","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/6_7fc70880-0664-4aac-8663-c2db93f3a289.jpg?v=1747823197","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_be13a776-ac74-4f5c-94ca-dba878291dc8.jpg?v=1747823197","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_4b837134-e1d2-48f9-bf11-12ed3b4f8ffd.jpg?v=1747823197","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_17317633-03cd-4dad-8f56-d52e79b67b2e.jpg?v=1747823197","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/4_c19546fe-eb49-41fb-be12-8acfd3dd7df1.jpg?v=1747823198","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/5_c21e9c26-7fe0-4815-adde-42fe88fc7b62.jpg?v=1747823197"],"price":69.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:45.047Z"},"share_url":"https://firestarter.network/l/lst_vxLS2ZzI","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
