The chip has here an independent power supply allowing it to reveal its full potential.\n\n\n\n\n\nEmbedded Altera Max V CPLD\nThe embedded Altera Max V CPLD incorporates a number of technologies, including clock management, PLL, DoP decoder and digital filters.\n\n\n\n\n\nI/V Conversion\nThe X18 has no less than eight independent I/V converters, each dedicated to a channel of the DAC, using OPA1612 AOPs. These offer excellent measurements with extremely low distortion and noise levels. Resistors with a tolerance of 0.1% are used for the key sections of this I/V converter.\n\n\n\n\n\nAccusilicon A5318-B Clocks\nTwo Accusilicon A5318-B clocks ensure perfect synchronization of the audio signal for a particularly low jitter level, promoting clear and pure playback.\n\n\n\n\n\nXMOS XU216 USB Interface\nThe USB input of the X18 uses an XMOS XU216 interface. It supports high resolution streams, up to 32bit 768kHz PCM and DSD512, while ensuring accurate and neutral sound.\n\n\n\n\n\nBluetooth 5.0\nThe Gustard X18 features Bluetooth 5.0 reception, allowing you to stream your music remotely, for example from a smartphone or tablet. The integrated chip supports the high-definition transmission codecs aptX HD and LDAC, ensuring sound quality equal to or better than CD quality.\n\n\n\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_2_001c5b59-c2c2-4671-a54d-101620d7324f.jpg?v=1661996233","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_1_1beaabb5-20f8-4d87-ac1b-658e3c083810.jpg?v=1661996233","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_4_07498690-ad7c-46b4-bd53-50755d3ecc22.jpg?v=1661996233","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_6_b06ffc26-3049-4252-988b-1cf196f886b5.jpg?v=1661996248","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_3_c35f960c-eb4b-4e48-bc23-ca87e0ef9b34.jpg?v=1661996252","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_5_8d11134e-81d3-4c5e-a5f3-56c39bdebba0.jpg?v=1661996273"],"price":749,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.297Z"},"share_url":"https://firestarter.network/l/lst_Q0FQGJ2L","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
