A heavily-shielded 120 W transformer minimizes interference while supporting clean power delivery. \nExcellent Clarity, Low Distortion\nSonically, the amplifier is praised for its spacious, balanced presentation and clean, delicate sonics—earning high marks for both sound and design. Its THD+N is around 0.001% @ 1 kHz/300 Ω. \nRobust Build and Desktop Presence\nA hefty unit at 12 kg and 330×110×380 mm, the GA‑10 sports a minimalist aluminum and steel chassis with functional ventilation and classic tube glow. It's built like a tank, with solid front-panel controls. \n\nFlexible Input/Output & Impedance Matching\n\nIncludes balanced XLR and RCA line-in options, plus output impedance switching (Low for <60 Ω, High for 60–300 Ω). Three headphone outs cover balanced XLR, 4.4 mm, and 6.35 mm formats. \n\nProduct highlights\n\n\n3W per channel (300 Ω); 600 mW (32 Ω), single-ended push-pull SEPP architecture\nTube complement: ECC83/12AX7 ×4 and EL84 ×4\nShielded 120 W toroidal transformer; disciplined voltage/regulator design\nTHD+N ≈ 0.001% @ 1 kHz/300 Ω; frequency bandwidth 20 Hz–24 kHz ±0.5 dB\nInputs: balanced XLR, RCA; Outputs: XLR 4‑pin, 4.4 mm, 6.35 mm\nWeight ~12 kg; footprint ~330×110×380 mm\nIdeal for high-end, high-impedance headphones (e.g. Susvara, HE1000) \n\n\nSpecs\n\n\nOutput Power: 3000 mW @ 300 Ω; 600 mW @ 32 Ω (@1 kHz)\nTHD+N: 0.001% @ 1 kHz / 300 Ω\nFreq Response: 20 Hz–24 kHz ±","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-ga-10-desktop-tube-headphone-amplifier-1176357864.webp?v=1751559650","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-ga-10-desktop-tube-headphone-amplifier-1176357863.webp?v=1751559647","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-ga-10-desktop-tube-headphone-amplifier-1176357861.webp?v=1751559641","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-ga-10-desktop-tube-headphone-amplifier-1176357862.webp?v=1751559645","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-ga-10-desktop-tube-headphone-amplifier-1176357860.webp?v=1751559639"],"price":1599,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.424Z"},"share_url":"https://firestarter.network/l/lst_aSbbyLVF","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
