{"type":"firestarter.listing","listing":{"id":"lst_MkKbCdJ7","product_name":"SMSL PA200 Gallium Nitride Power Amplifier","category":"Speaker Amp","description":" \nPower that adapts to every listening style\nThe SMSL PA200 is a power amp built for audiophiles who value power, flexibility, and detail. Buy one to use in stereo mode at 85Wrms per channel at 8$\\Omega$, or buy two to use in mono mode and unlock up to 400Wrms at 4$\\Omega$—enough power to handle passive speakers with serious demands. Its gallium nitride (GaN) transistor design runs at switching frequencies up to 1MHz, which helps vocals sound a bit clearer and percussion land more crisply. Dual inputs (RCA and XLR) connect easily to different source components, and carefully selected audio-grade components work beneath the hood to deliver stable, transparent playback. \nGaN: a new frontier\nGallium nitride transistors are a newer semiconductor technology that can switch signals at higher speeds and with fewer losses than many traditional silicon components. In practical terms, this means the PA200 can handle signals with more agility and less distortion. By reaching switching frequencies up to 1MHz, it supports tighter control over the audio waveform, helping notes hold their natural shape instead of becoming smeared or dulled. This greater accuracy, combined with the transistor’s ability to run efficiently without excessive heat, allows the amplifier to push challenging speakers without strain. \nMono mode for a boost in power\nWith a flip to mono mode, two PA200 units combine to drive speakers with four times the power. This higher output can handle more demanding loudspeakers. \nPeak performance \nWith a total harmonic distortion plus noise rating at 0.003% and an SNR above 100dB, the PA200 offers performance numbers that let you sink into the sound. \nWide bandwidth for full-spectrum sound\nFrom shimmering cymbals to the lowest registers of a thumping bass line, the PA200’s wide frequency response and dynamic range let music come through without it feeling boxed in. \nProduct highlights\n\n\nAdvanced gallium nitride transistor design for refined, stable sound\n\n\nSwitchable s","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264670241004.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264670109932.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669716716.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669487340.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669552876.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669618412.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669520108.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669585644.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669651180.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669683948.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669454572.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264669749484.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264670175468.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264670142700.jpg?v=1749051338","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-headphone-amp-smsl-pa200-gallium-nitride-power-amplifier-42264670208236.jpg?v=1749051338"],"price":419,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:58.013Z"},"share_url":"https://firestarter.network/l/lst_MkKbCdJ7","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
