客人分享⚡Bonn N8 AGD switch⚡用後心得
▪️▪️▪️▪️▪️
出色而又廣闊的大型聲場。 沒有太多自己的聲音特徵。 但是可以肯定的是,它使低音變得更深,更自然。 整體聲音非常乾淨細膩,對於任何系統升級而言,這無疑都是一個極不錯的選擇,對於比我更高端的Hi-End系統,我認為它應該更加出色! 聲音質量滿分10分,價值20/10分👍🏻👍🏻👍🏻
原文:Sound very good👍🏻👍🏻👍🏻 I didn't have any time to let it warm up before listening last time and didn't have much time to listen either 😅. Great big soundstage deep and wide. Not much on sound signature of its own except for the bass it goes deep and super natural. The improvement is just a very clean and detailed sound. It is certainly a good value for any system upgrades, but I suspect it must be even more fantastic for the more high end systems at the hifi show! 10 for sound and 20 out of 10 for value👍🏻👍🏻👍🏻

GRANDIOSO K1X
"Two revolutions integrated. Two revolutions connecting people to music... The VRDS-ATLAS and Master Sound Discrete DAC - now come to fruition in an integrated player that carries the name… Grandioso ( Grandioso (music): Grand or noble)."
An unprecedented transport mechanism that invites you to the furthest reaches of sound.
VRDS (Vibration-Free Rigid Disc-Clamping System) is Esoteric's unique CD/Super Audio CD transport technology, which has been specially designed to clamp the disc to a same-diameter turntable in order to eliminate the disc's rotational vibration, as well as any extraneous vibration emanating from the mechanism itself. It also corrects any warpage of the disc, dramatically improving the accuracy of both the optical pickup and the disc pit layer's corresponding optical axis, while also minimizing servo current. This all adds up to dramatically reduced disc read error for exceptional audio quality.
The new VRDS-ATLAS platform boasts unprecedented mechanical perfection and superlative audio quality, with heavyweight construction that is fully 127% heavier than previous iterations (6.6kg for the mechanism alone, and 13.5kg including its base). This highest rigidity and weight in the history of VRDS mechanisms has the effect of greatly reducing any and all vibration that could adversely affect audio quality. The transport's larger new side panels and bridge are all formed of SS400 steel, and its turntable is made from duralumin, which is renowned for its excellent sound quality. Also, its spindle features a newly designed thrust bearing system, for a friction-free one-point spindle support system that ensures smooth, noiseless turntable rotation.
Esoteric's impressive VRDS-ATLAS is the quietest and most elegant transport in the history of VRDS. The key to achieving this was a resolute focus on mechanical grounding technology that more effectively reduces vibration.
Adopting a wide & low-profile design for the entire mechanism helped achieve a lower center-of-gravity, and relocating 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 stored.
The Grandioso K1's mighty power supply was the key to its powerful and profound three-dimensional sound. With the introduction of its new X version, this power supply has been dramatically enhanced to add further depth to its exceptional audio tone. Its built-in D/A converter features independent power transformers for left and right channels, and the K1X includes a total of four independent toroidal power supply transformers. Furthermore, technologies cultivated in the development of the Grandioso P1X/D1X have also been adopted, including a new low-feedback DC power supply regulator featuring a discrete circuit configuration which contributes to its powerful open sound. The K1X also contains a total of 76 EDLC* supercapacitors (with a total capacity of 2,050,000µF or 2.05F). This greatly increased power supply capacity provides a tremendously improved sound quality for exceptional resolution in the lower frequency ranges.
*EDLC (Electric Double-Layer Capacitor):A special type of capacitor boasting an astoundingly high capacity compared to the electrolytic capacitors used in conventional audio equipment.
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 four 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 the power supply wiring.
Semi-Floating Top Panel
The enclosure's top panel utilizes a screwless semi-floating structure that further contributes to an open and expansive sound.
Master Sound Discrete DAC
Bringing out all the dynamics and energy of the original master recordings.
Master Sound Discrete DAC Bringing out all the dynamics and energy of music.
Unattainable by integrated chips, our goal was to assemble carefully selected and tested discrete components into a complete circuit that could perfectly reproduce all the dynamics and energy of music. Our top engineering teams put their pride on the line to design and produce a quality of sound that can only be found in the Master Sound Discrete DAC discrete D/A converter.
The K1X's Master Sound Discrete DAC is the most revolutionary two-channel stereo DAC circuit in Esoteric's history, and is based on the original circuit developed for the Grandioso D1X monaural D/A converter.
As an extension of the D1X's design philosophy, a luxurious volume of materials have been invested in the construction of K1X's Master Sound Discrete DAC. For example, it features 32 separate elements for each channel. Key components such as a clock driver, logic circuit, and capacitors and resistors, are kept independent for each of these 32 elements to ensure the purest output without no loss of musical energy.
The K1X's independently developed Δ∑ modulator supports 64-bit/512Fs and the latest high-end digital formats, including of 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.
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.
The ESOTERIC-HCLD output buffer amplifier boasts an amazingly high-speed slew rate (response speed) of 2,000V/µs. Current transmission and speed—the most important factors for an analog output circuit—have been pushed to the limits to reproduce the reality of music with a dynamic range that is truly breathtaking.
In addition to its XLR and RCA amplifier line connections, the K1X also features the ES-LINK Analog method of current transmission. Taking full advantage of the HCLD buffer circuit's powerful current supply makes the K1X 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.
A high-accuracy clock circuit is the key to achieving superlative sound quality in digital audio playback. A top-quality clock circuit is truly the heart of any high-end digital player. The K1X now 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 earlier model's internal circuitry and components to more vividly emphasize the K1X's ultimate audio quality while further boasting remarkably low phase noise and excellent center precision (±0.5ppm).
The K1X can also be connected to the Grandioso G1 Master Clock Generator for playback, with internal circuits synchronized to a 10MHz clock that features the same high precision as an atomic clock, enabling further pursuit of high sound quality.
D/A Converter Functions for External Input, D/D Conversion, MQA Support & USB Input
In addition to its coaxial and optical inputs, the K1X also features a USB type-B port that is compatible with both 22.5MHz DSD and 768kHz/32-bit PCM asynchronous signal transmission, thus enabling it to also be used as a stand-alone D/A converter. Functions are provided for upsampling a PCM digital signal to 2/4/8/16× (max. 768kHz) and converting PCM to DSD. The K1X is also compatible with MQA-CD decode playback and full MQA decoding for playback of various digital inputs including USB.*
*MQA certification is pending as of August, 2019, and support is scheduled to be added via a software update as soon as certification is complete.

To Innovate, the Workplace Comes to Class
將職場帶入教室的創新教學
In a sleek laboratory at Marshall University last month, four high school teachers hunched over a miniature steam-electric boiler, a tabletop replica of the gigantic machinery found in power plants.
上個月在美國西維吉尼亞州馬歇爾大學一間造型優美的實驗室裡,四名高中老師朝向一台微型蒸氣電熱鍋爐弓下身。這是發電廠裡巨大鍋爐的桌上型複製品。
They hooked the boiler to a small, whirring generator and tinkered with valves and knobs, looking for the most efficient way to turn coal, natural gas, nuclear or solar energy into electricity.
他們把鍋爐連接上一台嗡嗡作響的小發電機,調整閥門和旋鈕,尋找把煤、天然氣、核能或太陽能轉為電力最有效的方式。
The teachers, who were attending a summer training program, are helping West Virginia in another kind of transformation. Long one of the poorest states, it is now leading the way in turning vocational education from a Plan B for underachieving students into what policymakers hope will be a fuel source for the state’s economic revival.
這些參加暑期訓練專案的老師正在幫助西維吉尼亞州進行另一種轉型。向來是美國最貧窮的州之一的西維吉尼亞現在打起頭陣,要把職業教育從成績不佳學生的次要選擇,轉變成決策者希望的、這個州經濟復甦的一股原動力。
Simulated workplaces, overseen by teachers newly trained in important state industries like health, coal and even fracking — the energy industry's technique to extract oil and gas from rock by injecting high-pressure water, other mixtures, and chemicals, are now operating in schools across the state. Students punch a time clock, are assigned professional roles like foreman or safety supervisor, and are even offered several vacation days of their choice in addition to regular school breaks. (Many take time off during deer hunting season.)
現在,西維吉尼亞全州各地都有學校開辦模擬工作場所,指導老師都在這個州重要的產業如醫療、煤礦甚至液壓受過最新訓練。液壓是能源業的技術,透過注入高壓水、其他混合物和化學物,從岩石開採石油和天然氣。學生上下班打卡,被指派擔任領班或安全監督員等專業角色,甚至在學校例行假期之外可以自選幾天休假。(許多人在獵鹿季休假。)
Traditional math and English teachers have been reassigned to technical high schools, to make sure students on the vocational track still gain reading, writing and math skills.
傳統的數學和英文老師被調派到職業高中,以確保技職體系的學生仍掌握讀、寫、算技能。
And this fall, students enrolled in simulated workplaces will need to participate in one of the program’s boldest elements: random drug testing.
今年秋天,參加模擬職場專案的學生必須參與專案最大膽的項目之一:毒品隨機檢測。
Given the extent of the state’s opioid crisis, employers “wouldn’t take anything we were doing seriously until we passed that hurdle,” said Barry Crist, principal of the Fayette Institute of Technology in Oak Hill.
西維吉尼亞州橡樹山市「費耶特技術學院」校長克里斯特說,由於西維吉尼亞州有嚴重的鴉片類藥物危機,雇主「不會把我們做的當一回事,除非我們通過毒品這道關卡」。
West Virginia’s heavy push on vocational education comes as leaders of both parties have talked about making it a priority, a shift from the No Child Left Behind era of education reform, in which college for everyone was often the goal. In 2015, fewer than half of 25- to 34-year-olds nationwide had earned an associate or bachelor’s degree, according to census figures.
西維吉尼亞州力推職業教育之際,兩黨領袖也在討論優先推動技職教育,不啻告別「不放棄任何孩子」的教育改革時代,這種改革經常以「人人上大學」為目標。根據人口普查數據,2015年全美25到34歲的族群,獲有副學士或學士學位者不到一半。
“Vocational training is a great thing,” President Donald Trump said a week before Election Day. “We’re going to start it up big league.” In June, he signed an executive order that redirected federal job training funds toward apprenticeships, in which students learn skills at actual work sites.
美國總統川普在總統大選投票日的一周前說:「職業教育很棒,我們會大刀闊斧開辦。」他6月簽署行政命令,把聯邦政府職業訓練的專款改撥給學徒制,這種制度讓學生在實際工作場所學習技能。
