{"type":"firestarter.listing","listing":{"id":"lst_0gCQm5rR","product_name":"FiiO CP13 Cassette Player","category":"Cassette Player","description":"Aluminum Body Stereo Cassette Player\nThe FiiO CP13 is a modern portable cassette player built for listeners who want a reliable way to enjoy tapes with clarity and ease. It delivers fully analog playback, a custom balanced magnetic head, an oversized pure copper flywheel, and a 13-hour lithium battery.\nDual-mode power supply for continuous listening\nThe CP13 runs on a lithium battery that recharges through a simple USB Type-C connection. Its charging circuit is designed to remain stable under use, so you can listen while charging without stressing the player. This keeps the focus on the music rather than power concerns.\nCompact frame that fits easily into daily carry\nThe CP13 is built to be as slim as the cassette movement allows. Structural refinements keep the body to just 1.25in (31.8mm), giving you a portable player that slips cleanly into a jacket pocket or bag. This size makes it convenient to keep tapes part of your everyday listening without extra bulk.\nDual-color aluminum body for durability\nThe aluminum chassis uses a dual-color finish and visible fasteners that complement the player’s shape. Its buttons undergo hard oxidation, improving wear resistance over time. The analog volume knob turns smoothly and provides better tactile control than thin potentiometers often used in compact players.\nFully analog playback chain\nThe CP13 uses an all-analog circuit from the magnetic tape head to the amplification stage. This uninterrupted path preserves the natural qualities of tape playback. The result is consistent analog sound with a character that matches the format’s strengths.\nAudiophile op-amp JRC5532\nInside the CP13 is the JRC5532, a well-known dual op-amp appreciated for its stable behavior and clean output. In this circuit it supports low distortion and smooth channel performance. Specs like THD+N ≤ 3.5% and SNR ≥ 55dB reflect the unit’s measured consistency.\nCustom balanced magnetic head\nThe magnetic head is selected from a small portion of production that","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-dap-digital-audio-player-fiio-cp13-cassette-player-transparent-1213272593.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623972.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623966.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623969.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-dap-digital-audio-player-fiio-cp13-cassette-player-transparent-1213272591.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623973.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623967.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623970.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-dap-digital-audio-player-fiio-cp13-cassette-player-transparent-1213272594.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623974.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623968.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623971.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-dap-digital-audio-player-fiio-cp13-cassette-player-transparent-1213272592.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-dap-digital-audio-player-fiio-cp13-cassette-player-transparent-1213272590.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623978.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623979.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623977.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623976.jpg?v=1774436737","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-apos-fiio-cp13-cassette-player-transparent-1209623975.jpg?v=1774436737"],"price":87.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:56.817Z"},"share_url":"https://firestarter.network/l/lst_0gCQm5rR","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
