&$×nbsp; π£ &nbε>∞sp; &✘§¶nbsp; ™★φ Design Philosophy : ♠±Moving Away from USB A♦≤¥φudio
The GLD1.0 was design©∞¶₩ed to eliminate the widely¥★ε• used USB audio protocol, which is comγ¥₽monly found in many digital players an¥↓↔d Hi-Fi audio devices. Instead, the sy♠π↓λstem employs the high-speed PC≈πIe transmission protocol, ®→₽which includes a robust error-c×↓>hecking mechanism. This change ensure¶☆s that audio data is transmitted witho ☆ut errors or loss, preventi →¥γng damage to sound quality. Th§₽e USB audio protocol allows for errors £∞™☆or modifications in the data during t♥↕ransmission to maintain continuiα↕↔ty, which is a major reason why≥£ digital players using USB audi®↓γo protocol often fail to achieve pe♠₹rfect sound quality. In contrast, σ§PCIe is a protocol that does not all±Ωow any data errors, ensuring the i 'ntegrity of the data.
During the digital proce♦®ssing of audio data, when the ε€♦✔playback software reads the data, no ≠ββπerrors occur. Whether the ★π∞system is Windows, Linux, or Androi✘≈d, all file systems haveα₽® mature and stable error-checking mec∏¥hanisms to ensure the correctness ↑♦→₹of the data. These err♦ααor-checking mechanismsλ≈•☆ are primarily manage≤ε >d by the hard disk controller (ECC↑∏, CRC) and the file system (metadat♣¥§£a and data block chec®★•ks), ensuring data integrity. For criΩ♣★tical or sensitive files, applicati∏π→ons often add extra hash checks ♠"(such as MD5, SHA-256) to guara♥÷←ntee security and correctness.
Under normal usage conditions,←< the error rate of modern hεσ§ard drives is very low:
Consumer-grade hard drives: Approx∑↓imately 1 error per 12.5TB
Enterprise-grade hard driv•×es: Approximately 1 error per 125TB
Modern SSDs: Approximately 1 error per ↓<1.25PB
Modern computer operati→∏™ng systems are highly stable and reli¥✔±able, the probability of hard disk read♥≠ γ errors is very low and<•¶§ can be negligible. They can read data f☆∏rom storage perfectly&"< . So why doesn't this perfect ✔↔¶'data result in perfect sound quali÷×ty? The reason lies in the fact that→Ω most audio players use the U★σ×≥SB audio protocol for data >•≈×output. During transmiss∏₩ion, data is lost, leading to degrade♠∏d sound quality. Therefore, th'>εe transmission process musα↕t be optimized.
In the file data reading and s®¶torage phase, since →≠it does not involve clock synchroniza☆α•βtion, the hardware design during this±'← phase has little impact on d<←ata accuracy. Improving hardware, such φλ↕as enhancing power circu £its or using high-precision clock☆™•s, does not help ensure data↕γ× integrity. To fundamentally addre∏↓★ss the issue, the root cau✘γ↑©se of the sound qual≈÷™ity degradation must be identifi₹♠ed.
Since the probability of error<∏πs in reading file data from the fi&βle system is extremely low, the only pσ®₩ossibility is that the issue occurs d÷λ€÷uring data transmission. Many di↑♣gital players use the USB au>λ§dio protocol in their int•'♠&ernal data transmission process,≤§ and since the USB audio protoco★•$πl allows data errors, tγγhe problem lies here.
Therefore, the transmission method must☆ be optimized. The USB audio₹' protocol must be abando→☆↓ned in favor of a transm₹ission protocol that does not al↓↕γαlow errors. GLD1.0, t§ herefore, chose PCIe.
Replacing the USB audio protocol with↔ ✔ PCIe for transmissi ↕§"on and working in synchronou¥∞₹s mode is a highly chal ¥≠↑lenging task. To achieve this design, t× he GLD system incorporat≠¶es a complex clock and data system,¶↔ as well as a unique POW dat§↔>a clock transmission protocol. This ar∏ £chitecture has been granted a ♥ ©♣national invention patent of Ch₽•ina. After several years of relentless π≈§effort, GLD1.0 successf≥£↔ully realized this design δ→goal.

Digital Processing Syste₽¶m
The digital processing system is ✔♥connected to the main cont>≥rol system via a PCIe interface, ★πusing the PCIe protocol to transm ¶it audio data from the main boar∞φ∏d to the digital processing p≥←™art. This system consists of se×βven subsystems: ✔✔receiver, isolatoε↑∏r, data proces ¶₽sing module, cl♦↔ock module, POW♣→☆ transmission module,&nbsφ€p; SPDIF module, and ↔Ωpower supply. &¶λ☆λnbsp;It is equipped w₩♣✔∞ith firmware using com>plex algorithms that allow PCI∑≥₩e to operate in synchro♠∏♦nous mode, processing data and c₩€locks at high quality and outputting • them perfectly.
POW Transmission Module
A key highlight of the GLD1.0 is ©'σthe POW transmission module. POW stands forφ₹ "Parting of the ↔αWays," a term which means "go♦ ing separate ways.&qu♠↕ot; This is the protocol used by the GLD1.0 to outpπ₹↓ut processed audio data. It is aπ©±™ proprietary protocol developed bφ₹y Cen.grand, and is cu ∞rrently only used on their d¶¶igital players and DACs. &εαλ→nbsp;As the name suggests, "par↑π♦ting of the ways" me®×↕ans that the clock and data are transm✘✔Ω≤itted separately. Audio data is transmi∑tted via optical fiber, whil↔πe the clock is transmitted using↑ ★ coaxial cables with BNC connectors<<≠∏. The POW receiving module at φthe DAC receives ★ε✔≤the data and clock, then recombφines them into an I2S signal and sen§≤•d it to DAC.

The POW transmission protoc<αol is a pioneering model←§≤ in the Hi-Fi audio fi$eld. It allows high-qu±&£®ality transmission of both data ↑'☆ and clocks. Due to the use of ™δ↕₹telecom-grade invisible♣ασ light transmitters and rec$↓eivers in the optical α♦>fiber transmission, its ∏₩←bandwidth reaches the G-level an✔±d transmission distance ≠♠extends to kilometers, making it idσ÷₹eal for short-range transmission of ¶☆£₽M-level audio data with ease.

The GLD1.0 is a high-performance∑•≤© digital player suppβ<∑orted by multiple innovativ±↓φ€e technologies, with its digital clo↑★ck architecture having been granted λ↔←✘a national invention patent.
PCIe Synchronous Transmission Tech™÷₩nology
The foremost technology is the PCIe sy<∞βnchronous transmission teγ÷→chnology. Through a carefully des$↔igned interrupt mechanism and cooσΩ₩rdination with the host system, P↓₹CIe transmission achieves synchronou§♣♦s operation, allowing audio data✘≥↕ to be transmitted without errors γor packet loss from the mai•₹™n control system to the data pro πcessing system. Compared to USB audiφ→&o protocol transmissiφ↑α on, this method ensureδΩ•s complete transmission of audio da↑☆¥ta, offering advantages that USB∞≈↔ audio cannot match.
Clock System
The clock distribution mana gement module is one of the core techn•<ologies of the GLD1.0. High-qual≥→ity femtosecond clocks, through a comp↓∑≈lex distribution mechani₽≥sm, synchronize the op™↑eration of the PCIe host syst<em and the receiver, p≥©≠roviding synchronized clock< ±s for the POW output module and∑≈♥< SPDIF output.
POW Transmission and Reception Techn♦" ≤ology
This is one of the high✘'lights of the GLD1.0. By separa↕♦♦ting the transmission of d 'ata and clocks, it avoids the damage© that SPDIF encoding mechanisαΩms cause to clock quality, allowin✔¶←g the DAC to receive high > -quality clocks from the front-end di±☆≈gital turntable, similar to∑δ∑ an external independent clock confi€λguration. Telecom-grade optical fibers σ↕with G-level bandwidth, capable of tra π nsmitting over kilometers, ea<☆♥€sily send data to the♣©£ POW receiver module. The receivεε↕>ed data and high-quality cloc✔$≥k are recombined into an I2§π∞S signal and transmitt↔<•ed to the DAC. This transmiss≠≠÷ion mode is currently thσ✘§"e most advanced digital audi>o transmission technology in the Hi-Fi≥α field.
Electromagnetic Isolation Technology
To prevent the complex electrom≈∞$agnetic conditions of t πhe main control system from i€×±nterfering with the dig ∑ital processing system÷♦9;s clock, the GLD1.0 i♣€✘ncorporates electromagnetic isolati☆®♣on between the main con✘ trol system and the digital processing §<₽←system. This physical±©✔σ separation ensures the digital syste♦♣×m remains unaffected by interfe∏ &rence, thereby guaranteeing clo$≤∑✘ck quality.
The improvement in sou∞♥nd quality brought about b₽ y 100% data integrity is unmatched by☆÷>Ω any other method. The data loss and m<☆§≈odification inherent in USB audi&♥¥o protocol cause severe★> ¥ loss of sound detail, leading many→✘ Hi-Fi enthusiasts to adopt the be α↑lief that "digital playback ♥γ≤ cannot match CDs," a widely♣ § accepted view in the Hi-Fi co♣¥mmunity for years. The advent of the G≤♣LD1.0 can change this perception. Wi™★φth complete data, the details in theβ → sound are greatly enhanced, harmonics→ are more pronounced, and the sense of ↔÷presence is significantly incr¶↑eased—all characterist♦♠ics of high-end audio equipment.
