Many friends suggested to add a USB interface, Lao Zhang considered repeatedly, combined with everyone’s opinions, and considered actual needs, so there is this version. The standard version adds a USB version, and the Pro version also adds a USB version. So far, 1541 The decoding will stop updating and will not appear in any subsequent versions. . .
Using the industry-recognized USB asynchronous receiving solution xmos, with excellent circuit design and powerful secondary phase-locked loop circuit, it can guarantee extremely excellent digital output and provide a strong guarantee for the entire sound reproduction. . .

Due to the adjustment of the price of individual special chips and output transformers of this machine, the original selling price of this machine is no longer able to support, so the price of this machine is adjusted synchronously, hereby explained.
Explain: Many people always like to ask this kind of question, “How is your product better than XXX”For this kind of question, Lao Zhang will not answer this question. As a seller, I don’t want to step on others to raise it. Gao Zi, although shopping malls are like battlefields, one has to have a minimum bottom line. This is also a basic respect for others, and buyers ask the sellers how the products are, it feels really a bit redundant, and my children certainly don’t. Will say bad, so I hope to understand. . . . .
Many people confuse the built-in phase lock of the DAC chip with the external two-level phase lock. The general DAC chip uses the primary phase locked loop technology in order to achieve the purpose of reducing the time base jitter. But one phase lock is far from enough. For example, the famous CS8412 and CS8414 digital demodulation chips, its one-time phase-locked loop time base jitter can reach a level of only about 200ps, which is far from the 50ps required by the professional level. Distance, and the clock is not only a requirementJitter rate,The secondary phase-locked loop will automatically track the working state of the input signal, that is, the synchronization state. Therefore, many people hope to use the built-in phase lock of the chip to achieve high sound quality. It is basically impossible to achieve... Among the excellent decoding, the two-level phase-locked loop and synchronous shaping clock stabilization technology has attracted the most attention.

AsCDThe originator of the machine, Philips developed to1541There will be no follow-up highBitChips come out, with the strength of Philips, the development is higherBitChips shouldn’t be difficult, it’s more of a different concept, just likeChief Designer of MarantzK.I.

As one of Philips’ classic chips,TDA1541AThe most commendable is the high-density intermediate frequency including human voice, and the performance ability of small signal strength changes.,Just likeLPThe data specifications are far less thanCD, But a well-trainedLPThe system can bring a more realistic touch. Some people say that this is "musicality", but a clearer and easier-to-understand term is actuallyTDA1541AIt allows you to listen to music for a longer time without feeling tired at all,CDListen one by one without realizing it! Maybe this is already discontinuedTDA1541AIt can still last forever, the reason why it still has a place in the audio circle.
Looking at the vast majority of the marketDIYDecoding is basically in accordance with the officialPDFThe manual recommended circuit is made, and the production difficulty and cost can be controlled relatively low. Looking at the top foreign decoders, all of them are usedDSPCompared with the two-stage phase-locked loop circuit, an excellent phase-locked circuit is expensive and the components are hard to find,Since this machine was positioned at the mid-to-high end at the beginning of its development, it was used as an individual20The anniversary edition was launched. The original intention of the design was uncompromising. The development was completed in half a year. The whole machine adopts imported advanced components and eliminates all the difficulties on the components. It is committed to creating an excellent DIY decoder.Reference PhilipsLHH1000Flagship decoder, feel the real1541Sound, the secondary phase lock circuit,Professional audio industry20Commemoration of the year, to the greatTDA1541pay tribute!
