KEF has announced the Universal Wireless System 2.0 that transmits CD quality sound to two speakers, using advanced, proprietary technology to eliminate interference with potentially conflicting devices. As well as featuring enhanced software and a more powerful transmitter, the all-new KEF Universal Wireless System 2.0 is available at £450.00.
CD Quality Sound
KEF Universal Wireless System 2.0 delivers CD quality sound -- providing, of course, the source is also CD quality and transmissions are not significantly degraded by physical barriers. There is no need for wiring between speakers, as it includes two receiving units, each of which features a 50W amplifier that ensures rich sound with minimal latency.
Eliminates Interference
To guard against interference from devices such as Wi-Fi routers, microwave ovens and mobile and cordless phones, KEF Universal Wireless System 2.0 uses a narrow signal band. Coupled with KEF's advanced error correction technology, this results in exceptionally robust delivery of audio between the transmitter and receiver.
http://forum.ecoustics.com/bbs/messa...381/674947.jpg
"The KEF Universal Wireless System 2.0 is ideal for music and movie lovers who wish to eliminate wiring between amplifiers and speakers, allowing them to create an outstanding listening environment without the need for clutter or compromising sound quality. It can also transmit sound from
devices like computers and MP3 players, with a signal capable of powering speakers in nearby rooms and even outdoors."
-- Steve Halsall, Managing Director,
KEF's UK Business Unit.
KEF Universal Wireless System 2.0 also employs technology known as Advanced Frequency Hopping Spread Spectrum (AAFHSS). A detector continually searches for potentially conflicting transmissions, and if any are found the system "hops" to a different channel, keeping the signal stable. The process takes just milliseconds, so users don't notice it is happening.
Ideal for Home Cinema -- and Stored Music Collections
KEF Universal Wireless System 2.0 dovetails perfectly with most audio speakers, and electronic components with 3.5mm standard audio jack connections. Primarily designed for home cinema enthusiasts who do not want AV wires trailing across the room to rear speakers, it is ideal for 5.1 home cinema systems, and a second KEF Universal Wireless System 2.0 set can enable expansion to a 7.1 system, with no signal conflicts. KEF Universal Wireless System 2.0 works with popular modern audio players such as PCs and iPods -- allowing users to enjoy stored music collections on their premium speakers.
Setup is simple. Users connect the transmitter to a sound source, and each of the two receivers to a speaker and a power outlet, and KEF Universal Wireless System 2.0 is ready to deliver sound -- with no wizards to run, buttons to press or dials to turn.

目前的訊源是fm tuner + SACD player
目前計劃從桌上型電腦連接usb dac到擴大機
但這個不會是主要的訊源,推測聲音會比SACD player差
但如果想完全數位流呢?
出售SACD player，換成筆電+usb dac
fm tuner維持不變
那我那些SACD怎麼辦?如何轉檔?(sweat)
SACD還有CD層
不過何必賣SACD呢....
我就都有呀.....
無線通訊進入「秒殺時代」！清華大學物理系教授潘犀靈領導國科會研究團隊，成功利用一千億赫茲（100GHz）載波頻率研發出傳輸速率高達每秒二百億位元（20Gbit/s）無線通訊關鍵技術和系統，可在一秒內下載十部片長兩小時的高畫質ＤＶＤ電影，成為全球速度最快的無線通訊系統。
與現有３Ｇ手機傳輸速率每秒二百萬位元比較，國科會研究團隊研發的「超高速光電無線通訊技術」，傳輸速率是３Ｇ手機的一萬倍，直接帶動無線通訊技術向前跨越兩個世代。
國科會工程技術發展處長李清庭指出，由潘犀靈領軍的清華大學、交通大學和中央大學跨校研究團隊，在超高頻超高無線通訊領域已建立許多關鍵技術，居全球領先地位，有機會發展成為都會型無線通訊網路主流。
潘犀靈表示，隨著智慧型手機普及和超高畫質３Ｄ影像時代來臨，現有３Ｇ或研發中的４Ｇ無線通訊技術，都很難滿足消費者在未來十年內對頻寬和速度的使用須求。
潘犀靈指出，光纖網路雖然擁有足夠頻寬，卻缺乏無線通訊的機動性，「超高速光電無線通訊技術」結合有線與無線兩種通信系統，可以把傳輸速率提升到每秒二百億位元，而且傳播到幾十公里外，也不會影響訊號清晰度。
日韓已投入六百億赫茲無線通訊技術研發，預估在五年內上市，清華大學光電研究所助理教授黃承彬表示，我國通信業者可以直接跳過六百億赫茲，在一千億赫茲做好技術布局，把戰場拉到「下下世代」。他透露，研究團隊可望在今年暑假將載波頻率拓展到一兆赫茲，把傳輸速率提升到每秒一千億位元以上，提升通信業競爭力。
Human Audio Tabla SB Interface
The development at Human Audio turns to PC-based listening as well. At end of this way one new device has born: "Tabla" which was the missing link from the people who wants to listen music from the PC on the higest level. With this new device we're able to connect our existing audiophile / high-end DAC (or the next generation "Libretto HD" CDP) with the PC in order to listening audio streams up to 24bit/192kHz. Tabla needs only one free USB 2.0 port on the PC and the output is a coaxial digital (BNC or RCA) for the DAC direction. Based on the Human Audio philisophy this device is purely battery powered with the built in two pieces high-grade Lithium-Iron-Phosphate (LiFeSO4) cells. The charging is fully automatic without any external device since the Tabla could use the USB power for charging purpose at idle times. The Tabla can provide ultimate audio performance through the totally independent smooth battery powering, ultra-low jitter circuits, specialized pulse transformer and of course with one of the best USB-Audio algorithm on the market. (Mac OS and Windows based PC's are supported)

Abbingdon Music Research's new DP-77 [$4.995]
Abbingdon Music Research's new DP-77 [$4.995] with its Gemini Digital Engine allows selection between a 16-bit non-oversampling chip and a 32-bit chip for a 'best of both worlds' approach between legacy Redbook CD and PC-audio high-resolution files. The 24/192 USB input is asynchronous and there are minimum-phase apodizing reconstruction filters to minimize pre-ringing. The DAC's 'global master timing' clock is adaptive to avoid stepped matching to incoming sampling frequencies. Instead it scans continuously between 28.000.000 discrete frequencies to mirror the incoming data rate perfectly.
Four of the nine digital inputs work through a tube buffer and in preamp mode the DP-77 offers 71-step analog volume control with a resistor array.

光纖頭 下載40GB藍光光碟秒殺
- <LI class=ui>2011-04-28 <LI class=ui>中國時報
- 【李宗祐／台北報導】
電腦、手機、電視和隨身碟等資通訊和消費性電子產品訊號傳輸及連結，進入移光「換」影的新世代。中央大學和交通大學跨校研究團隊以光纖取代銅線傳輸訊號，成功研發出全球速度最快的「矽微型化光學連結晶片組」，僅須「瞬間一秒」就可傳輸下載容量達四十ＧＢ（四百億位元）藍光光碟。
現有電腦和手機等資通訊產品互相連結的ＵＳＢ（通用序列匯流排）連接頭傳輸速率約○．五ＧＢ，「矽微型化光學連結晶片組」則提升到八十倍，晶片組成的光纖頭比姆指還小，長寬各僅○．五公分，是全球最精巧的光纖晶片組。
依研究團隊測試速度，未來應用各項資通訊產品，在ＵＳＢ完成連結瞬間，資料隨即以「秒殺」速率傳輸下載。
中央大學光電科學與工程學系副教授伍茂仁形容，「我們讓傳統ＵＳＢ接頭傳輸速率從飛機邁入噴射機階段！」研發成果已陸續獲日、美、歐盟和中國大陸等多項專利。目前全球ＵＳＢ接頭每年市場需求達廿五億個，以每個三到四美元計算，產值近百億美元，這項研發成果可望成為我國資通訊產業邁向光子新世代的祕密武器。
經濟部技術處科技專家詹文鑫指出，最大突破是把現有資通訊產品以銅線傳輸改為光子傳輸，傳輸速率加快，也解決電路基板銅線排列越來越密造成的干擾問題。面對全球激烈競爭，我國研究團聚站在最前緣的領先地位。
研究團隊估計，兩、三年內，電腦、手機和隨身碟等資通訊產品就能普遍使用光纖頭連結及傳輸訊號，邁向「秒殺」世代。
小叶，你好！
以前拜读过您关于audionet家访，印象很深。
关于数码音源，我一直认为将来也是必然的趋势。
我觉得用IMAC做为讯源接入MAP1 （火线接口）会是一种比较好的做法？不知您怎么看？
另外这部CHORD DSC 900 您了解吗？
呵，不是未來趨勢，已經是進行式了....
MAP1有火線輸入喔？應該是自己的資料傳輸(如VIP)，不能用MAC吧....是不一樣的
CHORD DSC 900 我不瞭解喔.....應該是早期的產品

那个火线应该是audiolink自身输入的左边那个。可惜我无法上图。
那個火線是自家用的，跟一般Firewire功用不同
這台有USB Audio
小弟有去參加這個發表會, 但這報導說法有誤..該模組傳輸速率40Gbps沒辦法一秒傳完40GB
未來是真的很有可能把光收發模組整合到cable裡, 且看新一代的USB, HDMI或Thunderbolt會如何發展吧
