RP2000谁介绍介绍？
新出来的RP2000是个什么妖精？弄得RP1000都没了？安润好像RP8.1下架了？ :lol 按照问题帝的一般规律，问过的东西通常是要买的:lol RP2000-V8 the "Rudi Stor legacy concept amplifier"
The most classic and pure solutions matching the high tech. The Hi Tech items are not just a gadgetbut real functional instruments, with the function to control the most critical electrical functions so the amplifier can work always in the best conditions.

The basics 1 The use of two aerospace designed switchingpower supply ( followed by a redundancy of traditional capacitance)ensure high current, highest reliability, no EMI or any kind ofemission and the cleanest output current,as requested by the very severe aerospace specifications, are ever more severe, so we select the best only before mounting on the RP200-V8 The panels on the front are too from aerospace industries and are not just panels but small touch screen computers, they perform an initial check of all the function of the amplifier, if test passed the amplifier is ignited, then every minute a check of the bias ofeach of the 8 tubes will be performedin background, the bias is auto adjusted constantly,so the tube always work at their best The right onboard computer have also the function tocheck the temperature of the most critical components, inorder to properly adjust some values to match the environmental conditions. The left onboard computer after a start up procedure display the level of output signal,while in background arerecorder the hrs of work of each session and the total hrs of usage ( * information available only connecting a PC to a USB port, need a service program )
The basics 2 Preamplifier by 8 Tubes ( 4 x ECC82 x Channel) selected and crio treated (not replaceable to any other tube), 8 power transistor working in trans-conductance mode, oversized current mirror in order to have the highest current available..
The touch of warmth given by tubes followed by very high current of bipolar power transistor, is our tradition for best VT sound. No Negative feedback is another tip adding transparency and detail to the sound.

The start up checking:Voltages, tube and transistor bias are checked, right screen indicate the Amplifier serial number
When on normal operation the screen indicate the main voltage ( a complete check is performed every second in background)while the right screen indicate the sound pressure level for each channel
http://www.rudistor.com/w2.jpgWhen on normal operation the screen indicate the main voltage ( a complete check is performed every second in background) while the right screen indicate the sound pressure level for each channel
http://www.rudistor.com/2k3500.jpg The Result The sound is transparent clean very detailed and dynamics and there is no way to describe it. It must be listened.
The construction is Made in Italy totally in aluminum, with 10mm thick faceplate and 4mm panels. All components come form the best available production including aerospace and military high tech production and selected to match our severe standards, RP2000 V8s is tough and reliable and rock solid made.
RP2000 as a pure high end amplifier work in balanced mode only and must be connected to a balanced source: if an unbalanced source is connected the output will be unbalanced ( trough 6.5mm jacks)
The St-By switch work as " heater stand by " it disconnectthe main DC voltage to amplifier but keep the tube pre-heated ready to go back suddenly to work
*a unit ofRP2000 will be visible at Rudi Stor office and show room in Hong Kong

这个不是早就有听感了吗？问题帝都火星了吗？

來自意大利的耳擴專家Rudistor，一直不少高級的平衡耳擴，早前推出旗艦產品RP2000-V8，售價達$102,800，最近亦到了位於香港Jaben的Showroom。Jaben Hong Kong的負責人表示現時全球只得2台RP2000-V8，1台位於Rudistor本部Office，另一台就在大家眼前作試聽之用，如果不想買Demo，就要等大約半年時間才有新機。RP2000-V8為前膽後石的設計，使用8支ECC82膽作前級放大，電源部分及顯示面板用上航天科技設計，電源部分為切換式設計，無電磁干擾，令電源供應非常穩定；機身面版的兩塊屏幕，有關方面表示跟平板電腦上的完全不同，並非為美觀或多媒體功能而設，是用來顯示機內運作情況，一般操作時都會顯示運作的電壓，而每次開機時都會檢查電壓、膽管、晶體管的狀況，機身的編號也會儲存及顯示，非常個人化。線路上完全獨立，平衡輸入時亦需要使用平衡耳機連接，RP2000-V8於意大利原廠製造，外殼為鋁金屬，使重量達18kg。
售價：$102,800

个人听感
香港J店的电力质素越搞越差，完全浪费了RudiStor 的高价耳放
音源方面也太垃圾了，买得起RudiStor高价耳放的人（303或以上)，最少也有五六千元的音源吧
服务方面有待提高.
幸好有030在，可以试一试两者差距，先听030还是和以前一样，中低频不够好，不够底气
之后转到RP2000上听，明显音场大了两三个圈(电力质素差关系，音场电力正常来说音场只一般而矣)，底气回来了，密度高左几多下
RP2000是用八支12AU7做出来，行胆的机(做得好)是比石机有水份湿润,自然不少的，030高中频很不错，但就是欠了一种湿润,松软，自然不做作的感觉 而RP2000就有了
总结来说:今次听RP2000只能肯定比030好一至两个档次，但置于是否值10W的耳放我也得不到答案
题外话:听RP2000时会有明显底噪，这些底噪不是RP2000设计失误所致的，而是电力太差RP2000太灵敏关系先听到的，030是听不到
我曾经用求败由L店去J店，在L店没底噪很好声的(在场有两个朋友可证明的)去到J店有明显底噪 声又缩哂水变得一般了(两个朋友也一起去了J店可证明的)
而030是没底噪的，曾经以为音源关系，没接信号线一样有事，音源试过用金鹿接640C来听可惜一样凋谢了(没什么起色)
概况起来两个字，坑爹！
具体来说，第一是价格极度坑爹
第二是用开关电源，比RP1000还缩了:lol :lol
回复 7# 的帖子
声音听下来还是明显比030有密度和稳定很多的，即使只是用了RCA...价格就不好评价了，就是一个你愿意付多少去提升效果的问题... 听说交钱后等半年，把一般的人都吓跑了。 交钱后等半年，官网公告价格下调20%:lol 当时我纠结是搞这个还是WOO那个一万美金的分体铝疙瘩，最后都没搞。
也许今年会出来新旗舰。 原帖由 shengyuzhong 于 2012-2-29 15:44 发表 http://bbs.headphoneclub.com/images/common/back.gif

价格下调没机会, 最怕出货后官网立马发布RP3000 ;P 原帖由 palchiu 于 2012-2-29 15:49 发表 http://bbs.headphoneclub.com/images/common/back.gif
