THIS BADBOY IS NOW FULLY UPGRADED AND READY TO SERIOUSLY ROCK YOUR WORLD!!
JRC4556 Dual Op Amp!
3X Nichicon GOLD Audio Capacitors!!
Have you always wanted an RA-1 amp, but just couldn't afford the hundreds of dollars it costs to have one? Here is the PERFECT alternative! This amp includes the SAME chip that is used in the RA-1's that sell for hundreds of dollars! What makes this amp even better is that it's handmade, and enclosed in portable awesome tins (which I have a variety to choose from). And it comes with a LIFETIME warranty! Now that's a deal that can't be beat =) That makes these amps truly unique and very rare. Not to mention that these makes a great conversation piece!
The headphone amp is built on a professional Printed Circuit Board (PCB) handmade by me employing principles used in HI-END audio. All audiophile-grade parts are carefully selected for the best possible sound quality through long experiments and listening sessions. The amp is hand built and tested by me. It includes top-of-the-line components including Switch Craft, Alps, Dale Vishay, Upgraded Wima Capacitors (installed in the signal path for the lowest noise possible), and Nichicon.
This amp can greatly improve the sound quality of your headphones and boost the weak output of :
CD Players, MP3 Players, Ipods, PC, Laptop soundcards, Home Stereo, and more.
FULL LIFETIME WARRANTY ON ALL MY AMPS =)
求达人分析一下，外观什么的实在是比砖头啥的好看啊


我看到了有史以来最简单的电路板

饭盒

这外形

这还真不算最简单的。

薄荷糖？！

**，这造型奇葩了，分明是拿个糖盒往里塞各种东西，感觉挺像玩具。

电容啥的看不懂啊，达人快来

简易二房？

等等，45美刀？
那不就是代表着换算成软妹币只要将近300块？

自己窝在家最多三天可以焊出差不多的。。

就是个cmoy而已....

好像在俱乐部还是大家谈上有看到过，记得是美国烧友的DIY耳放

能详细点不？高手们别藏着掖着啊~
如果还OK的话可以考虑弄一个玩玩

在打架上也看过= =

很复古
