VRDS (Vibration-Free Rigid Disc-Clamping System) is a core technology of ESOTERIC’s CD/Super Audio CD transport mechanisms that has been a key point of focus since the brand’s founding. The system firmly clamps the disc onto a turntable of the same diameter, thus eliminating both the rotational vibration of the disc itself and the effects of any extraneous mechanical vibration. Any latent disc warpage is also corrected by the turntable to significantly improve the relative optical axis accuracy of the optical pickup and the disc pit surface, while also minimizing servo current. This all combines to significantly reduce disc read error and further enable breathtaking sound quality.
「VRDS（Vibration-Free Rigid Disc-Clamping System）」是品牌創立以來，ESOTERIC持續專注於CD/SACD轉盤機構的核心技術。除了透過與光碟同樣大小的轉盤確實固定住光碟旋轉，還要澈底消除光碟本身在旋轉時的振動與機構本身多餘的振動，而且還要透過轉盤矯正光碟的扭曲，大幅度提升光學拾取與光碟表面的相對光軸精確度，並將伺服電流降到最低，因此大幅度降低了光碟讀取的錯誤，達到更優異的音質。
Adding VRDS-ATLAS to the K-03 series
The VRDS mechanism has undergone continuous development and improvements for over 30 years. Throughout its long, illustrious history, one prominent highlight has been the debut of the VRDS-ATLAS platform, which offers the pinnacle of perfection and sound quality. The K-01XD is equipped with VRDS-ATLAS mechanisms that have been specifically customized for each model in order to carry on the full qualities of the VRDS-ATLAS reference mechanism used in our flagship models, the Grandioso P1X and K1X.
K-01/K-03終於內建「VRDS-ATLAS」
VRDS機械機構是經由超過30年的持續進化才完成的成果。在那輝煌的歷史中，最亮眼的就是擁有最高水準的完成度和傲人高音質的全新平台「VRDS-ATLAS」誕生。K-01XD/K-03XD配備了專用於每種型號的VRDS-ATLAS機構，完全繼承了旗艦款（Grandioso P1X、K1X）所採用之「VRDS-ATLAS」頂級機構的質量。
New Version of VRDS-ATLAS: ATLAS 03
The K-03XD’s ATLAS 03 system employs a simpler 18mm-thick bridge that requires far less machining. The mechanism boasts ultra-high rigidity and a weighty design to damp out any vibration that could affect sound quality. The transport’s duralumin turntable also has a well-earned reputation for excellent sound quality, and its solid steel bridge is larger than that for the VRDS-NEO, using a one-point spindle bearing design that minimizes friction and rotational noise through its point-contact thrust bearing, which utilizes the same steel ball featured in the high-end models.
2樣全新的「VRDS-ATLAS」-「ATLAS 03」
K-01XD所配備的「ATLAS 01」，跟高階款一樣採用20mm厚的鋼橋。而K-03XD所配備的「ATLAS 03」則是減少加工部位，採用18mm厚的簡單鋼橋。兩款機械結構都以極高剛性和重量見長，能夠減低影響音質的振動。轉盤部分是用音質受到好評的杜拉鋁合金製成，SS400的鋼製鋼橋尺寸比VRDS-NEO還大，心軸軸承也跟高階款一樣，以鋼珠和止推軸承形成點接觸，將摩擦和噪音盡可能抑制到最少。
Wide, Low Center-of-Gravity Design
As the quietest and most elegant transport in VRDS history, ESOTERIC’s impressive VRDS-ATLAS epitomizes the company’s resolute focus on mechanical grounding technology in order to more effectively reduce vibration.
Adopting a wide, low-profile design for the entire transport mechanism helped achieve a lower center-of-gravity, while the relocation of the turntable motor to below the turntable from its previous position above the bridge dramatically shortened the route for grounding vibration and reducing mechanical noise. Tray hollowing has also been minimized for increased rigidity, and special stoppers made from vibration-absorbing elastomer cancel out resonance when the tray is in its closed position.
又寬又低重心的設計帶來了最佳的抑振
「VRDS-ATLAS」是VRDS史上最安靜也最優雅的，而成功的關鍵就在於有效抑制振動的機械接地技術。機械結構整體不但寬闊，更以低矮的寬薄設計，讓它變得低重心。而且還把過去置於鋼橋最上方的轉盤驅動馬達移到轉盤下方，大幅減低了接地之前的振動，從而降低了機械的噪音。托盤因為把挖空的部分盡可能減到最少，所以提高了剛性，加上採用了特殊的吸振彈性體樹脂作為制動器，所以在收納托盤時能夠有效防振。
High-Performance Power Supply – The Key to Sound Quality
The key to the powerful and deeply luxurious sound quality of the K series has always been their high-performance power supplies. This new XD edition features a significantly enhanced power supply design that delivers even richer, more lifelike sound. The K-03XD features a total of two high-capacity toroidal power transformers with independent power supplies for the digital and analog circuitry.
成為音質關鍵的強大電源電路
K系列以強大又輪廓鮮明、立體的聲音見長，其音質的關鍵就在於強大的電源部分。此次更新的XD版本，對電源部分進行了大幅度的強化，因此音色更加深邃。K-01XD總共採用了4顆大容量的環形變壓器，數位類比轉換器部分的左右聲道和機械結構以及數位電路，各自從專用的電源變壓器供電，非常奢華。K-03XD則是總共採用了2顆環形變壓器，讓數位和類比的供電個別獨立。
New Low-Feedback DC Regulator and Super Capacitors
The higher capacity design of the K-01XD and K-03XD power supplies enables remarkable improvements in sound quality with enhanced resolution in the lower ranges. Their low-feedback DC power regulators minimize feedback in a discrete configuration that does away with integrated circuits by utilizing technology originally developed for the Grandioso P1X/D1X, resulting in a powerful, expansive sound. The K-03XD uses 26 super capacitors (total capacitance: 650,000μF).
內建全新的低回授DC調節器 / 超級電容
導入開發Grandioso P1X/D1X的技術，電源調節器採用「低回授DC調節器」，不使用積體電路，改用分砌式結構，將回授量抑制在最少，讓聲音充滿強大又開放的感受。另外，K-01XD總共用了71顆（總容量1,850,000μF=1.85F）超級電容（大容量電容），而K-03XD則是26顆（總容量650,000μF=0.65F），藉由增加電源容量，讓低頻的解析度等獲得顯著的提升。
Chassis Construction and Parts Layout
The VRDS-ATLAS transport mechanism is centrally located within the chassis, where it is fixed to a 5mm-thick steel bottom plate and supported by three proprietary pinpoint feet (patent no. 4075477 and 3778108). This effectively isolates the rotational mechanism from vibration. The internal structure of the chassis features a double deck design, with the audio boards on the upper level and power supply circuits and transformers on the lower level to minimize magnetic flux leakage and vibration, while also shortening power supply wiring.
箱體結構和部件配置
將VRDS-ATLAS轉盤機構置於中央位置，以5mm厚的鋼製底板固定，透過獨家的腳座（專利第4075477號、第3778108號）採三點支撐，藉此有效抑制旋轉機構的振動。箱內採用雙層結構，上層是主要的音響電路板，下層則是配置電源電路和變壓器之類的，不但能預防漏磁通和振動，還能將電源供應的配線最短化。
Semi-Floating Top Panel
The enclosure’s top panel utilizes a screwless semi-floating structure that further contributes to an open and expansive sound.
懸浮式頂板
頂板不用螺絲固定，採取半懸浮的結構，讓聲音能夠伸展，帶有開放感。
Bringing out all the dynamics and energy of music
Our goal was to assemble a carefully chosen selection of rigorously tested discrete components into a complete circuit that could perfectly reproduce all the dynamics and energy of music – something simply unattainable using ordinary integrated chips. Our top engineering teams put their pride on the line to design and produce a quality of sound that can only be found in our Master Sound Discrete DAC discrete D/A converter.
把仔細檢查過的分砌式零件組成電路，藉此實現積體電路所無法達成的音樂「躍動感」和「能量」。賭上ESOTERIC頂尖工程團隊自尊的聲音表現，在完全自家設計的分砌式數位類比轉換器「Master Sound Discrete DAC」下實現。
Luxurious Materials for Powerful Electrical Current Output
The Master Sound Discrete DAC was first introduced in the Grandioso D1X as the most innovative DAC in Esoteric history, and its astoundingly realistic sound quality has consistently drawn rave reviews for causing listeners to feel as if they were at an actual live performance. The version featured in the K-03XD uses a simpler circuit configuration that incorporates the very essence of that found in the K1X to carry the 03 series models to new heights. Consisting of 32 elements per channel, each DAC element includes clock drivers, logic circuits, capacitors, resistors, and other component parts, while each group of 32 elements is kept isolated from the main parts. In keeping with D1X design philosophy, these DACs are packed with a luxurious selection of state-of-the-art components to ensure the pure, effortless output of boundless musical energy.
大量物資的投入和強大的電流輸出能力
「Master Sound Discrete DAC」是ESOTERIC史上最具創新的DAC，最初用於Grandioso D1X，其活生的聲音表現獲得了高度的評價。K-01XD/K-03XD裝置的版本濃縮了K1X版本的精華，因為簡化了電路結構，所以讓K-01/K-03兩個系列提升到更高的層次。DAC每聲道由32個元素構成，每個元素由時脈驅動、邏輯電路、電容、電阻等元件組成，32個元素的主要配件全都是獨立的，所以投入了大量的物資，原汁原味發揚了D1X的哲學，將音樂的能量毫無保留地純淨輸出。K-01XD因為奢侈地採用了頂級的高音質元件，進一步實現了高音質。
Advanced Digital Processing
The K-03XD’s independently developed Delta-Sigma (Δ∑) modulator supports 64-bit/512Fs and the latest high-end digital formats, including 22.5MHz DSD and 768kHz PCM signals. The FPGA’s dedicated digital processing algorithm was developed exclusively for the Master Sound Discrete DAC, and has been fully optimized for outstanding playback of both DSD and PCM digital audio data.
高端的數位處理能力
內建獨家開發的ΔΣ調變器，能支援64bit/512Fs，以及以DSD 22.5MHz為首的最新規格重播。為了以最佳的FPGA數位處理運算來重播各種規格的PCM，ESOTERIC特別為「Master Sound Discrete DAC」開發了專用的FPGA演算法。
Advanced Quality Control
With a discrete DAC, where component tolerances are directly linked to arithmetic precision, highly advanced quality control is also required for the manufacture of electronic circuit boards. ESOTERIC’s own in-house factory boasts some of the world’s leading board mounting technologies, such as soldering performed in an oxygen-free furnace, which is located in a clean room featuring the same level of cleanliness found in a hospital operating room. Technologies cultivated in the production of electronic circuit boards for audio, medical, aerospace, and defense industries support the high production quality of the Master Sound Discrete DAC.
來自嚴格品管的高音質
分砌式DAC的運算精確度會受到元件的品質落差影響，所以電路板的製造也需要追求高水準的知識和品管。ESOTERIC的自家工廠採用跟醫院手術室同等級的無塵室，在裡面使用無氧爐焊接，擁有全球少見的黏著技術。也正是這樣源於音響、醫療、航太、國防相關的電路板製造技術，在背後支持著「Master Sound Discrete DAC」的高品質。

Luxurious Materials for Powerful Electrical Current Output
The Master Sound Discrete DAC was first introduced in the Grandioso D1X as the most innovative DAC in Esoteric history, and its astoundingly realistic sound quality has consistently drawn rave reviews for causing listeners to feel as if they were at an actual live performance. The version featured in the K-03XD uses a simpler circuit configuration that incorporates the very essence of that found in the K1X to carry the 03 series models to new heights. Consisting of 32 elements per channel, each DAC element includes clock drivers, logic circuits, capacitors, resistors, and other component parts, while each group of 32 elements is kept isolated from the main parts. In keeping with D1X design philosophy, these DACs are packed with a luxurious selection of state-of-the-art components to ensure the pure, effortless output of boundless musical energy.
大量物資的投入和強大的電流輸出能力
「Master Sound Discrete DAC」是ESOTERIC史上最具創新的DAC，最初用於Grandioso D1X，其活生的聲音表現獲得了高度的評價。K-01XD/K-03XD裝置的版本濃縮了K1X版本的精華，因為簡化了電路結構，所以讓K-01/K-03兩個系列提升到更高的層次。DAC每聲道由32個元素構成，每個元素由時脈驅動、邏輯電路、電容、電阻等元件組成，32個元素的主要配件全都是獨立的，所以投入了大量的物資，原汁原味發揚了D1X的哲學，將音樂的能量毫無保留地純淨輸出。K-01XD因為奢侈地採用了頂級的高音質元件，進一步實現了高音質。
Advanced Digital Processing
The K-03XD’s independently developed Delta-Sigma (Δ∑) modulator supports 64-bit/512Fs and the latest high-end digital formats, including 22.5MHz DSD and 768kHz PCM signals. The FPGA’s dedicated digital processing algorithm was developed exclusively for the Master Sound Discrete DAC, and has been fully optimized for outstanding playback of both DSD and PCM digital audio data.
高端的數位處理能力
內建獨家開發的ΔΣ調變器，能支援64bit/512Fs，以及以DSD 22.5MHz為首的最新規格重播。為了以最佳的FPGA數位處理運算來重播各種規格的PCM，ESOTERIC特別為「Master Sound Discrete DAC」開發了專用的FPGA演算法。
Advanced Quality Control
With a discrete DAC, where component tolerances are directly linked to arithmetic precision, highly advanced quality control is also required for the manufacture of electronic circuit boards. ESOTERIC’s own in-house factory boasts some of the world’s leading board mounting technologies, such as soldering performed in an oxygen-free furnace, which is located in a clean room featuring the same level of cleanliness found in a hospital operating room. Technologies cultivated in the production of electronic circuit boards for audio, medical, aerospace, and defense industries support the high production quality of the Master Sound Discrete DAC.
來自嚴格品管的高音質
分砌式DAC的運算精確度會受到元件的品質落差影響，所以電路板的製造也需要追求高水準的知識和品管。ESOTERIC的自家工廠採用跟醫院手術室同等級的無塵室，在裡面使用無氧爐焊接，擁有全球少見的黏著技術。也正是這樣源於音響、醫療、航太、國防相關的電路板製造技術，在背後支持著「Master Sound Discrete DAC」的高品質。
Unique ESOTERIC-HCLD Output Buffer Circuit with Enhanced Current Transmission
he ESOTERIC-HCLD* output buffer amplifier boasts an astonishing high-speed slew rate (response speed) of 2,000V/µs. Current transmission and speed – the most important factors in the design of any analog output circuit – have been pushed to the limits to reproduce the reality of music with a dynamic range that is truly breathtaking.
* HCLD: High Current Line Drive
獨家的電流傳輸強化型輸出緩衝電路「ESOTERIC-HCLD*」
ESOTERIC-HCLD輸出緩衝放大電路採用了驚人的高速元素，其用來表示反應速度的迴轉率高達2,000V/μs，所以才能追求對於類比輸出電路最重要的強大電流傳輸能力和速度的極限，重現令人屏息的動態範圍和音樂真實。
＊HCLD＝High Current Line Driver
High-Quality ES-LINK Analog Current Transmission
In addition to their XLR and RCA amplifier line connections, the K-03XD also features ESOTERIC’s ES-LINK Analog method of current transmission. Taking full advantage of the HCLD buffer circuit’s powerful current supply ensures that the K-03XD is less susceptible to the detrimental effects of impedance on the signal route. It also enables a more powerful signal transmission, fully driving connected compatible devices.
內建高音質的電源傳輸方式「ES-LINK Analog」
接駁擴大機時，除了LINE的連接方式（XLR、RCA）外，還採用了ESOTERIC獨家的電流傳輸方式「ES-LINK Analog」。藉由HCLD緩衝電路的強大電流供應能力，讓訊號傳輸路徑不容易受到阻抗影響，可以強力傳輸訊號，將支援的器材潛力發揮到極致。
Grandioso Custom VCXO II
A high-accuracy clock circuit is the key to achieving superlative sound quality in digital audio playback, making it truly the heart of any high-end digital player. The K-03XD features the superb Grandioso Custom VCXO II clock originally developed for the Grandioso P1X/D1X. This clock was developed with carefully considered modifications made to the internal circuitry and components of other earlier models to more vividly emphasize each player’s ultimate audio quality while further boasting remarkably low phase noise and excellent center precision (±0.5ppm).
The K-03XD can also be connected to a Master Clock Generator (G-01X or G-02X) for playback, with internal circuits synchronized to a 10MHz clock that features the same high precision as an atomic clock, enabling further pursuit of the highest sound quality.
* VCXO: Voltage Control-type Crystal Oscillato
內建「Grandioso Custom VCXO* II」
要讓數位重播達到高音質的最大關鍵，可以說是時脈電路也不為過。優異的時脈電路是Hi-End播放器的心臟，K-01XD/K-03XD採用的高音質時脈裝置「Grandioso Custom VCXO II」是為了P1X/D1X所開發的，將以前內部電路的模式和使用料件全部更換，更加專注於音質，因此相位雜訊極低，擁有傲人而優異的中心精確度（±0.5ppm）。另外，兩款型號也可以和主時脈產生器（G-01X和G-02X）接駁，讓內部電路與更高精確度的10MHz時脈同步，再一次提升音質。
