In order to achieve better results, various audiophile-grade capacitors are used regardless of cost, including Cerafine capacitors, red robes with gold characters, nicknamed Golden Prince capacitors, which are well-known in the audiophile circle, as well as STARGET series capacitors and RE series capacitors, which are all high-end products for recording engineers A large-volume active crystal oscillator is used to that the time base jitter of PCM2706 is very low, so that the sound produced has a sense of freshness This is purely for the sake of sound quality, and the design of the appearance is abandoned, resulting in a much larger volume than the general small tail, which is tentatively called a large tail Compared with the small tail with a volume of only the size of a finger, the sound quality is a dimensionality reduction attack. The sound is very delicate and transparent, the human voice is poisonous, and the high frequency is gorgeous<br><br>Product model: TDA1305T decoding headphone amplifier Output interface: 3.5 interface * 2 Input method: USB USB chip: PCM2706 Decoding chip: TDA1305T Decoding parameters: 16BIT, 18BIT, 20BIT/32KHZ, 44.1KHZ, 48KHZ Output power: 140MW/16 ohms Frequency response range: 20-20KHZ Power supply: USB power supply Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
