The twentieth anniversary commemorative machine, the flagship that year, only produced 800 units, priced at 7,000 US dollars, and RMB 5W that year. Army 5703 tube, selected matching. The advantage of military management is its long life（200,000 hours）, Strong anti-interference（The magnetic wave of the nuclear explosion works normally）, 24-bit decoding, a separate digital input, plus a digital interface, can be used as a decoder. The 5 transformers are independently powered, and the sound is not comparable to that of ordinary machines. After the machine is turned on for a while, the foot light turns blue, and the sound can be raised to a higher level. This excellent Tri-Vista SACD player. The design goals include:   [1] The top SACD sound quality performance   [2] CD restore performance exceeding Nu-Vista 3D    [3]"bulletproof"reliability   [4] External digital signal input   [5] Excellent manufacturing quality [1] The top SACD sound quality performance   Double-layer choke coil regulator system. There are one or two SACD players on the market, and the quality is indeed superb. However, Tri-Vista SACD has something that none of them have: our unique double-layer choke coil regulator system. This system brings huge advantages to the technical performance and sound quality of this SACD player, because the power supply noise has been reduced to almost zero. At the same time, the reverse noise outside the power supply system has also been reduced to a similar degree. This system makes each power transmission line in the machine become pollution-free, so that all components can work in the best condition, and there is no interference between each other.                                       Better power supply = better signal-to-noise ratio                                       Better signal-to-noise ratio = better dynamic range                                       Better dynamic range = better analytical power   A power supply system that is resistant to high-frequency noise interference.   SACD contains a lot of high frequency information and noise. They will bring great difficulties to the circuit system and power supply. We have designed a power supply system that can truly resist any noise and interference problems in the circuit. A major source of sound contamination is fundamentally eliminated.   Independent SACD and CD digital signal paths.   In addition, the signal pathways of SACD and CD are completely separated. The digital path of SACD has its own independent choke coil regulated power supply, DAC and filter. They have all been carefully tuned, and are specially optimized for the best SACD performance; the CD part also has its own independent choke coil stabilized power supply, DAC and filter, and it is also optimized for the reduction performance of CD Fine tuning and optimization. Because other manufacturers let SACD and CD share the same line, the two sources restrict each other, and the sound quality performance is compromised.   The output stage adopts 5703** tubes with performance exceeding nuvistor.   The output stage uses an amazing 5703 electron tube of the highest specification. In our opinion, it outperforms nuvistor in some aspects. Tri-Vista SACD has quite low output impedance, high damping coefficient, wide bandwidth, and ultra-low distortion. In addition, its output stage also has a Class A output capacity of about 5W. The purpose of such a heavyweight design is to be able to drive the load formed by the audio cable and the preamplifier. No matter how well-made the other parts of the SACD player are, if its output stage has problems with the drive amplifier and wire, it is meaningless. We have designed Tri-Vista as a source device that can drive any combination of amplifiers and cables. The end result is that all the information on the SACD can be most completely passed to the amplifier. [2] CD restore performance exceeding Nu-Vista 3D   Nu-Vista 3D is known as one of the best CD players ever. But we still decided to take it one step further. But because 3D is so outstanding, we can only make very limited improvements.（If major improvements can be made, is there any suspicion of participating in the 3D reputation?）   Tri-Vista basically follows the 3D DAC system, but uses 192K upscaling and an improved digital filter. In order to create something truly special, we added more choke coil regulator systems, cleaner power supplies, and an outstanding 5703 tube output stage.   The Tri-Vista CD player sounds particularly textured, and the sound density is quite good. The sound image focus has distinct levels, and the sense of depth before and after the sound field is extremely strong. For those who are accustomed to the performance of ordinary CD, the first time they come into contact with its sweet and pleasant sound quality will be very excited. We think the Tri-Vista CD player is better than 3D. As for how much higher it is, you have to judge for yourself. However, all the supervisors and R&D staff of music fax can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t wait to resell 3D and marry Tri-Vista. [3]"bulletproof"reliability   Reliability is one of the most important but often underestimated performance standards in every high-end equipment. The Nu-Vista series has achieved an enviable reliability record, so we decided to use it as a new construction basis. Every failure in 3D has been carefully analyzed to avoid possible problems in the future. All components have also been tested and evaluated to ensure that their performance can be best achieved.   Then, we also introduced the 5703** tube with extremely stable performance. As far as we know, this is the most reliable tube ever produced for it. Our early tests show that its failure rate is 1/3 to 1/4 that of nuvistor.   If all types of failures are included-including fuses, CD turntables, and random components, the failure rate of Nu-Vista 3D is about 1.5%. The failure rate of Tri-Vista SACD that we have calculated is below 1%. [4] External digital signal input   We have invested a lot of research and development work and time to produce this set of DAC circuits that can be regarded as one of the best in the world. The source can also benefit from Tri-Vista''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s excellent performance DAC circuit. [5] Manufacturing quality and aesthetics   We have invested a lot of cost in the processing and appearance design of the Tri-Vista CD machine. Exquisite silver processed by nine polishing processes"Moonstone"The surface decoration reflects a beautiful translucent brightness.   Feet. what! The feet will emit a beautiful blue light. But wait, they are more than that. When powering on, when the current stabilizes and the output stage is off, the feet are red.
