那还真不贵，还没有前面提的那个TKD的贵。可惜这些看上去华丽丽的好东西都是巨无霸的身材，挤不进小不点啊
khozmo的这个东西看上去也是挺YD的

东京光音的高阶电位器不错的, 但价位可以由千多二千元起跳

楼主的朋友改造mk8花了多少呀？觉得胆机推人声有天然的优势，看ebay上有些卖器材的原因就是上了全套电子管系统

他的朋友只换3粒fuse, 一对真空管, 能花多少时间

东京光音……听说很易坏掉……是很多DIYer的烦恼之源。

PENNY & GILES的RF11能称得上逸品，问题是逸品难求，不论是货源还是价钱。

你指的只是百多元级别的, 高阶的46级两联东京光音, 要三千多元一个, 日本部份的高阶扩音机所采用

khozmo应该是Ladder type的设计，比一般的步进要合理。

"The Ladder stepped attenuator is based around a 4-pole switch that selects individual pairs of resistors. With reference to Figure 1, each step is made up of two resistors, Rx and Ry, that forms the attenuation at that step.The advantage of having both resistors selectable is that the resistor values are chosen to provide a constant input impedance. In otherwords, Rx+Ry is constant for a given attenuator. This accurately mimics the effect of a potentiometer, but without any of the problems associated with the use of a wiper on a resistive track."

这个TKD两联制也不错的

Ladder stepped当然比步进的更好，毕竟每级声音只过两个电阻而不是23个（或41个）电阻全过。

C大我记得你推荐过一种平价的保险丝，是什么牌子来着？hifituning太贵了，买不起啊。

小白代理小不点吧，这个质量有保障的。

那就有意思了。

买就买自己喜欢的声音 就算没有品牌 只要听着满意 我一样购买 我家里的系统就是没有牌子的 一样

可以pk名机 但是必须自己可以接受这点才行 听音乐毕竟还是自己听得多 不用在乎别人的看法  

你去高保真听听潘志强的 土炮箱子

秒30万的世霸无压力。他那经常堆着上百万的系统，诶个比过来的。

此帖好火。。。
我还是比较喜欢我们家rpx33。。。

Head-fi上rpx33与小不点5的比较：

i'll make this quick since i'm not qualified to do a full review.

HD-650: they both drive the HD-650's fine.

the MKV is very detailed and neutral. certain sounds are just more distinct with it in the upper mids and treble. while i wouldn't call it harsh, it does veer a little in that direction when compared with the RPX-33.

the RPX-33 can come off at first as sounding less detailed. it has a way of presenting detailed highs in a really smooth fashion - no sharpness whatsoever. the sound is liquidy smooth, gooey, like you can melt into the music. overall, it's a more musical beast.

Denon D2000:

the MKV doesn't quite have enough current to drive these to their best. whereas the Rudistor presents a tight, punchy bass (as much as is possible with Denon's, at least), the MKV can leave it feeling a little more bloomy - still pretty good though.

overall, the MKV is a great value and sounds pretty darn good to my ears, but the Rudistor's extra refinement and power is what the extra dough gets you.

这个有人用过没

这是间没货交的厂商，之前hifidiy搞团购很多人热烈支持

可惜等了又等都没货交，有人收货都是次品来(坏的)

最近翻生了，但价格提升不少

之前四联都是 99元一个的，由于上次那件事后

现在信心太减，没人敢试

当初那啥diyaudio也有拿到，不过感觉是他家很小，出货挺慢的。。。而且现在的好像比当初的样子要yd了很多
