Dual 1794 HiFi DAC Optical Coaxial 24bit 1794A DAC OPA1612 OPAMP For Audio CD

Currently sold as the latest version, the regulator is upgraded to 3 pieces of LT1963 high-end regulator There are two versions of the machine: Standard version: op amp with 3 TL072 Upgraded version of op amp: op amp with 3 high-precision op amps from TI OPA1612 1794 has a sampling rate of 24bit 192K, has a high resolution, a sense of speed and transparency, and the tri-band is commendable, especially the human voice, mellow and sweet, and it is a cost-effective . After 2 pieces of 1794 are connected in parallel, the dynamic range and signal-to-noise ratio are greatly improved to 132dB. After parallel connection, the output current is doubled, the sound density is enhanced, and the human voice is obviously thick. The entire sound section is relatively balanced, durable, and low frequency. Also enhanced, because the signal-to-noise ratio is improved, the background also appears cleaner. Highlight 1: Dual-core 1794 decoding, details, dynamics, and sound field are all very good Highlight 2: The coaxial fiber input is demodulated by WM8805, which is a higher grade than the common CS8416 on the market, with low time base jitter and good compatibility, no popping, and easy transmiion of 192K 24BIT data Highlight 3: Using the National Semi-low distortion op amp OPA1612 low pa, the effect is better than OPA2604, the sound is transparent and delicate, and it is naturally bright. With a gold-plated IC seat, you can freely replace and upgrade the op amp Highlight 4: Using resistor-capacitor matching components and linear voltage regulator integration to make the circuit performance fully play, German red WIMA, ELNA capacitors, TDK high-quality resistors, etc. Highlight 5: The all-aluminum case with laser lettering is stylish and durable. Highlight 6: Excellent performance, but excellent price, because it is completely self-designed, and even the chais is produced by itself. In addition to the cost advantage, there is no other store that has more than 10 distributors to sell together, and the profits are all Eaten by the agent, so don't use the price to measure his quality. The package contains only one host, without optical fiber, coaxial and audio cables, which need to be purchased separately.
