今天終於有睡到5個小時，回台後再建立頁碼索引.........

[Leo Yeh]

請問這有機會團購嗎?

我會留意發行訊息的..............

[Leo Yeh]

今天再去T.H.E Show晃了一下，可說是相當冷清的一年，參展廠商很少，來的人也很少

每年都有藝人演出


買張唱片捧場一下，現場銷售人員還問我聽過沒，我說沒有，純粹試試


再買本書捧場一下，有夠重的一本






這喇叭真的不錯，去年的旗艦聲音也很棒，老闆很熱情

站大太操勞了~~辛苦啦~~~
小小提示....英文拼錯了....我很專心吧!!!

Wagatte推全新的Revolution系列，原本的就屬於為Classic系列
除了外觀不同外，Revolutino擁有更大的線徑，螺絲改為TORX型，然後內部夾片咬合更好

請問小葉站長這是什麼高音?

[XYouRtEAcHeR]

他使用的是現在PC散熱主流：熱導管

在銅管內側粗糙的壁上留下氣壓很低的水，遇熱立刻蒸發成氣體飄到溫度低的地方

然後碰到管壁立刻凝結，散熱速度可達熱傳導的好幾十倍

由於銅管內壁粗糙面有特別設計成具有虹吸效應的功能，水可以不斷由溫度低的地方補充到溫度高，水已蒸發的地方

請問站長

它有任何的對流冷卻風扇嗎？
它是否表示使用什麼冷媒呢？

Does it have any fan for forced convection cooling?

Does it indicate what refrigerant is used? Just curious.

請問小葉站長這是什麼高音?

這是台灣可音音響的喇叭
用的是氣動高音

SONY DEMONSTRATES PASS LABORATORIES’ 40th ANNIVERSARY COMMEMORATIVE VFET AMPLIFIER

High Power Class A Mono Design Incorporates Sony VFET Output Stage

LAS VEGAS, Jan. 7, 2014 – At a special press briefing held during the 2014 International CES, Sony Electronics joined with Pass Laboratories to demonstrate a unique high powered (250 watts output into 4 ohms) Class A amplifier which incorporates hand-selected Sony Vertical Field Effect Transistor (VFET) output devices.
This special model was developed specifically to commemorate the 40^th Anniversary of VFET technology, which was utilized by Sony and a handful of other companies in a limited series of amplifiers in the late 1970s.
According to Nelson Pass, founder and president of Pass Laboratories, “These historic amplifiers are now prized for their exceptional sound, which is a credit to their extraordinary linearity of their VFET devices. As a result, they established a benchmark for the next generation of solid state amplifiers which followed, that have become the reference standard in high quality music reproduction today”.
“Triode-like” Sound Quality
Sony’s VFET devices, also known as Static Induction Transistors (SIT), were smaller, less costly and much more efficient than conventional vacuum tube designs and were widely acknowledged for their “Triode-like” sound quality. Additionally, these transistors serve as extremely fast switching devices, which enabled Sony to introduce the first high-powered Class D audio amplifier in 1976.
This exclusive Pass Laboratories commemorative amplifier employs complementary matched pairs (2SK82 and 2SJ28) of Sony VFETs, which were in storage for nearly 40 years. The mono block amp operates in Class A mode, with a balanced circuit from input to output and no feedback required. The amplifier also includes a highly regulated stable power supply, which enables it to achieve 250 watts peak power into a 4 ohm load, with relatively low distortion (less than 2%).
In developing this product, Pass Laboratories utilized Sony’s highly acclaimed AR-1 reference loudspeaker, which proved to be an ideal match for the amplifier’s overall performance.
To celebrate this remarkable achievement, Sony Electronics will join with Pass Laboratories following CES in sponsoring a select number of demonstrations of this amplifier at Sony and Pass authorized dealers located throughout the U.S.
