It replaces the basic phono stages found in most turntables and amplifiers with a low-noise design, highly accurate RIAA equalization, and support for both MM and MC cartridges. With thoughtful engineering like an intelligent subsonic filter and symmetrical circuitry, it gives your records a cleaner, more detailed signal before it reaches the rest of your system.\nAccurate RIAA playback\nVinyl records are cut using inverse RIAA equalization, which must be precisely reversed during playback. The ZEN Air Phono 2 applies this correction with a tight ±0.15dB tolerance across 20Hz to 20kHz. That level of accuracy ensures tonal balance stays intact. Bass, mids, and highs are restored as intended, without coloration or drift.\nLow noise floor that reveals detail\nPhono signals are extremely small, which makes noise a constant issue. With an equivalent input noise as low as -151dBV, the ZEN Air Phono 2 keeps background noise well below the level of musical detail. Quiet passages remain clean, and subtle textures come through more clearly, especially on well-recorded pressings.\nIntelligent subsonic filtering\nWarped records can introduce low-frequency rumble that muddies playback. The built-in subsonic filter targets this unwanted movement without cutting into audible bass. By treating vertical and lateral groove information differently, it removes rumble while preserving the weight and depth of the original recording.\nMM and MC cartridge support\nWhether you're running a moving magnet or moving coil cartridge, the ZEN Air Phono 2 adapts easily. A rear switch adjusts gain to match your cartridge type, ensuring proper amplification without guesswork. This flexibility makes it easy to upgrade cartridges over time without replacing your phono stage.\nSymmetrical circuit design\nThe internal layout uses a symmetrical channel design, which helps reduce nois","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987208.jpg?v=1777580652","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987207.jpg?v=1777580590","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987206.jpg?v=1777580532","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987205.jpg?v=1777580469","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987204.jpg?v=1777580411","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987203.jpg?v=1777580350","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-ifi-headphone-dac-amp-ifi-zen-air-phono-2-1234987202.jpg?v=1777580290"],"price":129,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.823Z"},"share_url":"https://firestarter.network/l/lst_NdTHi2L7","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
