{"type":"firestarter.listing","listing":{"id":"lst_OQtaqUdk","product_name":"xDuoo CDM-10 High Performance Portable Tube CD Player","category":"CD Players & Recorders","description":"Dual DAC Tube CD Player\nThe CDM-10 brings the nostalgia of spinning CDs into the modern Hi-Fi era. Combining dual Cirrus Logic CS43198 DACs, dual Raytheon JAN6418 vacuum tubes, and \"tone switch\" feature, it delivers both crisp, detailed transistor sound and the rich warmth of tube playback at the touch of a button. \nDual DAC decoding architecture\nTwo flagship Cirrus Logic CS43198 DACs operate in parallel to provide high-resolution audio decoding with exceptional channel separation and low noise. Paired with a fully-balanced four-channel analog stage, the CDM-10 preserves subtle musical detail while supporting PCM up to 32-bit/384kHz, DSD256, and MQA playback through its USB input.\nTube and transistor listening modes\nThe CDM-10 features dual audio circuits that allow instant switching between transistor and tube operation. Transistor mode emphasizes precision, clarity, and expansive imaging, while tube mode engages a pair of JAN6418 vacuum tubes for a richer presentation with greater warmth, smoother vocals, and classic tube character.\nPortable vacuum tube implementation\nDual Raytheon JAN6418 tubes operate at low voltage and low power, making them perfect for portable use. An optimized shock-resistant circuit helps reduce microphonic effects while preserving the tube texture.\nCustom CD transport system\nA dedicated optical reading mechanism and custom servo system maintain stable disc rotation, precise tracking, and rapid error correction. This design improves disc compatibility while helping preserve the integrity of the original recording.\nDual vibration isolation design\nThe transport combines electronic cache memory with a physical damping buffer to reduce the effects of vibration during playback. By minimizing interference and jitter, the system helps maintain smooth and consistent audio performance.\nSelectable upsampling modes\nBuilt-in 2x and 4x digital upsampling modes allow listeners to tailor playback to their preferences. Upsampling reduces DAC filter workloa","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942142.jpg?v=1781178969","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942141.jpg?v=1781178908","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942159.jpg?v=1781178850","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942158.jpg?v=1781178732","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942157.jpg?v=1781178789","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942156.jpg?v=1781178670","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942155.jpg?v=1781178553","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942154.jpg?v=1781178610","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942153.jpg?v=1781178489","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942152.jpg?v=1781178372","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942151.jpg?v=1781178314","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942150.jpg?v=1781178429","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942149.jpg?v=1781178250","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942148.jpg?v=1781178191","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942147.jpg?v=1781182091","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942146.jpg?v=1781182032","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942145.jpg?v=1781181972","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942144.jpg?v=1781181852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942143.jpg?v=1781181913","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942161.jpg?v=1781181791","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-cd-players-recorders-xduoo-cdm-10-high-performance-portable-tube-cd-player-1243942160.jpg?v=1781181672"],"price":429,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.108Z"},"share_url":"https://firestarter.network/l/lst_OQtaqUdk","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
