如何打造現代化的High End系統？

[chen3058]

以音樂來說 USB 1.1 就可跑到24/96，USB 2.0 到24/192已沒問題
沒什麼規格戰吧？

是穩定的問題，測的速度不是看規格的，另外我說的規格戰指的是檔案、介面的規格，我目前看Apple就非常想主導檔案的型態、規格，MP3是一定不夠用，不好用的，但是這塊市場很大，很多大的公司都想指自己的發展方向當主導，沒那麼容易一下子就固定下來

這些早就固定了
檔案規格 WAV與AIFF、FLAC
介面就是同軸、AES、 USB、1394、網路

檔案以前不是有一陣子推APE，出局了喔

何況目前規格還是有幾個，我看要打到剩下一個

以介面來說1394穩定度比USB好，但是USB目前最多人用，今年底到明年電腦的USB3.0就會開戰了(Solution部分，目前主機板的部分，由ASUS的子公司和VIA目前進度領先，但是最穩的還是NEC，但是NEC沒有成本優勢，不太可能呈為主流)

APE明顯的不是主流，WAV是錄音室早就在用的格式，AIFF則是MAC系統無損主流

1394也是錄音室早在用
USB也因為最多人用，High End才會花心思去改寫得到好聲音

Audio要看到USB 3.0，一來沒有大大必要，二來可能要慢慢等
以規格，前述所說的已足High End使用

回到老話

什麼東西如果沒有需要，都可以慢慢等
就像買電腦一樣的道理....

但是以目前各家唱片公司目前的經營狀況來看，走向網路檔案的方式恐怕是對唱片公司有必要，但是新的經營方式（可收到錢又不被盜版）看來還沒辦法形成，所以目前看來CD還會是主流，個人的看法是商業模式解決後，大概進場的時機就不遠了

[Leo Yeh]

CD還是會主流沒錯
高解析是另外一塊市場，對High End來說更是
其實這幾年全球的CD不斷衰退
Download的銷售數字不斷上升

盜版的問題從CD-R就開始、MP3接續
我想這已不是他們要關心的

M2Tech發表了三款新品

hiFace Evo
hiFace 進化版
USB-to-S/PDIF interface, based on the same technology as hiFace, but with many improvements. Hosted in a stylish brushed aluminum case (105 x 100 x 46mm), with B-type female USB connector.

Main features
* input for external supply (7 to 11VDC)
* input for external Master Clock (BNC with transformer)
* 2 x S/PDIF outputs (RCA and 75 Ohms BNC)
* AES/EBU output with XLR connector and settable format (consumer and professional) by an internal jumper
* Toslink output
* ST output
* direct I2S output with 3.3V interface.

Some customers complained because of the lack of sampling frequency encoding in the S/PDIF stream of the present hiFace. The new model will have this fixed, for full compliance with the standard.

All outputs (except I2S) are transformer-decoupled to avoid ground noise and EMI interference. Three LED's indicate power, data stream in input and external clock presence.


Young 384/32 USB DAC
Stereo D-to-A converter in a nice brushed aluminum case and grilled front panel measuring 200 x 50 x 200 mm. Some of the highlights of this new model include:



* input sampling frequencies (kHz): 44.1, 48, 88.2, 96, 176.4, 192, 352.8*, 384* (* USB only)
* resolution: up to 32 bits (USB), up to 24 bits (other inputs)
* inputs: USB (B-type female), S/PDIF (RCA and 75 Ohms BNC), AES/EBU (XLR), Toslink
* outputs: single-ended on RCA
* supply: external 9 to 24VDC
* controls and display: standby, source select, large matrix display to show locked frequency and selected input


Vaughan 384/32 Reference USB DAC
The new M2Tech Vaughan is a high performance stereo D-to-A converter in a stylish brushed aluminum case and grilled front panel measuring 440 x 80 x 440 mm. Features of this high-end DAC include:

* input sampling frequencies (kHz): 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384
* resolution: up to 32 bits (USB), up to 24 bits (other inputs)
* inputs: USB (B-type female), S/PDIF (2 x RCA and 2 x 75 Ohms BNC, dual AES for 384kHz), AES/EBU (2 x XLR dual AES for 384kHz), Toslink (2 x for dual AES), ST (2 x for dual AES), straight I2S, external master clock
* outputs: single-ended on RCA and balanced on XRL, headphone on 6.35mm jack socket
* supply: 115-230VAC, optional high current lythium battery with battery changer
* controls and display: standby and select buttons, encoder, dual large matrix display to show locked frequency and selected input.

The M2Tech Vaughan will be our reference DAC and features 8 D/A IC's (4 per channel in mono mode). A digital dithered volume control will allow for using the Vaughan as a preamplifier. The headphone output is made with a discrete components amplifier.
