诺昌的价格应该从4折谈起
下次让你过去砍价 顶一下，居然台湾 越点音响有卖这玩意，我台湾人不顶不行，不顶不行:victory: 兔大已经完全脱离群众了
大多数人们都还折腾三大件的时候。。。 12AX7, RKV要用4只么？我这台老板HA-1A用2只，又想蹭听了！！:lol 原帖由 RickyLung 于 2011-6-1 17:52 发表 http://bbs.headphoneclub.com/images/common/back.gif801s确实一般，各方面都不及2900A 实话说81管子都是矮子里拔高个，在用的富豪6201虽然明显好于801s，但其实也谈不上有多好，2900和6201都已经是到头了的81王管了:L
几年前，朋友送我一对6201D斜环，
个人觉得这对T7声音太过HIFI。 据说胆机开机不放声才是最影响机器的？那位大大这样说的？

个人表示不赞同，机器开着，最关键的是必须带负载。否则容易烧牛。 我还是不玩胆了 原帖由 小夜叉 于 2011-6-4 13:20 发表 http://bbs.headphoneclub.com/images/common/back.gif我还是不玩胆了 无胆不欢 套套能不用则不用。 拿到TUBESOX，近乎完美的RKV体验 刚才写了半天，发帖的时候跳出来一个标题过长，然后一切就没有了，搞得意兴阑珊。
只能说这个管套的作用还有有的，作用大到比FE的避震钉的效果还大，声场更开阔，声音更细致，器乐的细节表现更好。我用的是风根的PCL805，声音的路数还是风根的，但素质和味道则在风根之上。
EAT Cool Dampers，不知道这个如何？

EAT Euro Audio Team的產品說明書譯文
The Cool Damper is a radical new device for the tube accessory industry from EAT – EuroAudioTeam. This beautifullycrafted audio product offers much more than simply adding a new styling twist to your valves by surrounding them in new, fashionable colors. It brings exceptional acoustic performance and function to your system by delivering sound that redefines the tube dampening category.
Carefully chosen materials for our Cool Damper device allows using it as a truly effective vibration-consuming damper. This results in reduced distortion from the tube circuit, as well as vastly reducing the tendency of most vacuum tubes to act in a microphonic manner. In addition, the sound from a component utilizing Cool Dampers can be heard to have more controlledand deeper bass, a cleaner sound stage, crisper and greater dynamic range, and better focus of the entire sound field.
The Cool Damper also reduces the operating temperature of the glass envelope of an electron tube by about 10 %, which of course acts to appreciably extend the lifetime of the tubes.
The Cool Damper is a result of many years of rigorous research and development. This high-fidelity, consumer friendly product is easy to install, and fabulously simple in design. We found, from all tested materials, that the most suitable is a relatively soft aluminum extrusion coated with a special blended mix of Teflon and Carbon composite PTFE. The precise shapes of the EAT Cool Dampers are finished with long-lasting anodic oxidation colors. This makes these cooling rings an aesthetically attractive, as well as functional, accessory for your valued vacuum tube equipment.
For flexible and easily detachable contact of the aluminum body to the sometimes erratic cylindrical surfaces of various tubes, we use six special carbon-teflon composite stripes (V profile). Appropriate design andmaterials of the Cool Dampers compensate for the naturally resonant tendencies of both glass and aluminum, and work to transform active vibration energy into thermal energy, which is then dissipated as heat radiation.
Tube dampers in one form or another have been around for many years, but these from EAT are so much more effective than any previous efforts that they deserve to be auditioned on their own merit.
How it works?
1. Dampers are from the factory preinstalled. This means 6 pieces of the V profiles are positioned in the middle of the hexagon.
2. By moving the V profiles along the face away from the corner it is possible to move it closer to the center of the hexagon and thus the valve wall. By this simple expedient, tubes from 19 mm to 22 mm in diameter can be accommodated, which covers most eventualities.
3. Diameters of the most valves are usually smaller on the top of the erratic glass envelope than on the bottom. By sliding the valve over damperin an up side down position (see picture on the right) you can easilyinstall it. In a case, damper slides down the glass or is to narrow just change position of the V profiles (see pictures A, and C).
Where do you use EAT Cool Dampers?
Inner side of the damper has 3 × 6 channels for a wide range of diameters from 19.5 to 22 mm. This means it fits to the following valves:
12AT7: ECC81, 6201, E81CC, ECC801, B309, 6060, 6679, 7728, CV455, CV2016, CV8154
12AU7: ECC82, E82CC, 6067, B339, 5814, 6189, 6680, 7730, CV491, CV8155
12AX7: ECC83, E83CC, ECC803, 7025, 5751, 7058, 7729, 6681, CV492, CV8156
6DJ8: ECC88, E88CC, 6922
EL84, EF86 and many others.
