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
Operational amplifier upgrade version: Operational amplifier with 3 high-precision operational amplifiers from TI OPA1612
PCM1794 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 chip. After 2 pieces of PCM1794 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. Also enhanced, because the signal-to-noise ratio is improved, the background also appears cleaner.
Highlight 1: Dual-core PCM1794 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 transmission of 192K 24BIT data
Highlight 3: Using the National Semi-low distortion op amp OPA1612 low pass, the effect is better than OPA2604, the sound is transparent and delicate, and it is naturally bright. With a gold-plated IC seat, it can be freely replaced and upgraded.
Highlight 4: The use of resistor-capacitor matching components and linear voltage regulator integration to make the circuit performance fully play, German red WIMA, ELNA capacitors, TDK high-quality chip resistors, etc.
Highlight 5: The all-aluminum alloy chassis with laser lettering is stylish and durable.
Highlight 6: Excellent performance, but excellent price, because it is completely self-designed, and even the chassis 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&x27;t use the price to measure his quality.
The accessories of this machine include 1 power cord, excluding optical fiber, coaxial and audio cables, which need to be purchased separately.
At this time, the famous Beijing Green Cube sealed transformer has the characteristics of low magnetic leakage and high efficiency. It is the most basic guarantee for the sound of the whole machine. Next to it is the high-speed filter capacitor for Panasonic FC audio.
