也给大家打打气--反碟先峰702摩摩版cdp

小弟都知三洋os金字比白字好多多,不过价钱不便宜,我没米[em00][em00],而且耐压都一般较低.唔知佢同黑闸blackgate电解比声音又边种好d呢?[em12]
兄台说的那种smd贴片式电容在香港那里可买到呢?你是不是在RS订的?我都想试下这电容.
我都知d线较硬,贪佢是双芯屏蔽镀银线,能同时传正负电又有屏蔽作用![em08]
兄台可否说说贴片式电容和RS线的型号小弟知,想了解一下!

AKMY5

我用的输出电容，就是那贴片式的，大的是10微/50V的，小的是22微/5V的
上次我在这儿和别人争论的就是这种电容，我把它当毒石了！（因为那种0。1微的有这种贴片的毒石！）
后来查资料，不是的！应该是叫片状陶瓷才对！有更加知情的欢迎补充！反正我试过的不管用来偶合还是滤波，都没发现好过它的！
还有就是5V耐压的我用到30V也一点问题都没有！放心用好了！

你再看看旁边的OS，给你推荐那种金字的，比一般标白字的性能好很多！

兄弟用的线还是不错的！但是布线也很讲究，它会在周围环境形成散布的场，同时也被周围原有的场所感应！考究的DIY，这也要讲究的！
所以我上个引线的图给你看看吧！而且能缩短的话尽量短些！

还有就是那个输出的偶合电容了！看你绑了一大堆，效果还是有的！但是建议你可能的话，试试我给你的下一张图上给的

布线的图：一般是三根绞在一起<img src="attachments/dvbbs/2005-4/200541614338471.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/200541614338471.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

最后再来张我用的过机线，在HK买的！感觉你的太硬了吧！能用这些会好点<img src="attachments/dvbbs/2005-4/2005416144157453.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/2005416144157453.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

这松下的大电容我都不喜欢,想改用Enla,等收到钳兄的clock板后一次做!
不知各位大大还有甚么改改建议?
[em05]

AKMY5

还没说完一按回车就发了！呵呵。。

还有一点最重要的还没讲！就是老兄的220V进线部分没有处理好啊！
那个EMI滤波你可以不用打洞的！把机壳都砸坏了！还有就是自己加的开关没处理好！开关不漂亮，后面露着电线，有触电的危险！！！这一点要千万注意啊！

不知道您是哪儿的，不过市面上不是有各式各样的热缩套管吗？
你可以把那个EMI滤波的电路板割小，接出线来，再用热缩套吹成一体绝缘的放到机器内，还有就是那个开关的后面也要用热缩套吹紧啊！

不過光頭壞了,不識貨已变成垃圾了[em11][em11][em11]

AKMY5

照我看它的DSP可能是CXD2500的！

我兄和我一样喜欢用利特的伺服电源板子！不过看你用的那几个大的电容不是很好！是松下的吧？根据我在功放里的经验，这中蓝皮的松下电容用在这儿会声音有些发刺！它的高频性能还是不错的，但是不知为什么，就是声音有些发刺！你认为呢？！
后面就近地贴OS，和我一样！不错！就近贴，效果才好！
只是那对偶合太夸张了！改天我给你介绍个试试！我看能不能上个图来！呵呵！让你试过再上来评价！

但也不象普通机那么左[em11][em11][em11]

501,801转盘好象在左侧,而702,802在正中的,使用光头亦不同的,D/A就要再睇下先!

好像501是一块板过的[em02][em02][em02]

也没带马达电位器，我理解应比701低一级[em08][em08][em08]

現在部先峰d聲音已超越我另外部cdp--飛利浦850MKII,同馬蘭士CD94比就各有千秋,這兩部cdp作改cdp的聲音參考,

現期待鉗版的clock板換上原本的晶體,另已訂左兩粒OPA637BP來代替627BP,637比627有更好的頻寬及轉換速率!

501到701到801到901.你的702应该是台湾版的排列[em12]

楼上主可否来张主板的照片，让我看看和501有什么不同。D/A是PD2026吧[em11][em11][em11][em11]

以下是引用文招在2005-4-16 0:41:00的发言：
那转盘比我以前用的501重料多了[em09][em09][em09]

702要比501後期的,改良左![em11]

而小弟曾换上opa2604,LT1057,5532,AD827但都不能全面.....
最后用超级靓声单运放OPA627BP,效果很好,声音质数全面提升.高低频两端都伸延得很好!

系运放opamp及交连输出电容,
一次不经意淘左这对飞利浦轴向电解,比起用开的enla电解通透,动态有力很多,人声有一种说不出的魅力,再并一UCC 0.1uf以改善高频信息量.

dac及运放的外围组件亦换上一些较优质的,如三洋os-con用系数字电源滤波有很好效果,加上一些小wima,银云母,五环电阻....<img src="attachments/dvbbs/2005-4/200541602321320.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/200541602321320.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
