ATOLL CD-100 很烂的, 是拿松下入门级CD机摩机的, 只改了一下电源和模拟电路.

为什么说他烂?
哪里有听?


因为是法国人拿YLJ 摩机的, 基础比CEC3300还差得远.

当然了, 我说他烂主要是心理作用, 没听过. "高保真"倒是推荐

说他烂是从它是从Technics SL-PG 490/590 CD摩机得来而说的,不是说声音.

Technics SL-PG 490/590 CD价格150美金左右.
不过如果你相信摩机可以提高N倍, 入门型可胜万元机的理论, 那我就不说什么了.

看看内部吧:

Tecnically speaking, the CD 100 is a traditional single-bit Japanese CD player with a new output analogue stage and a toroidal transformer that feeds it. A closer look at the inside of the CD 100 unveils its inner secrets.
The CD transport is a Philips VAM 1201/03 unit, used in many budget Japanese players while the digital circuits and audio boards (including the diminutive power supply transformer) are those of the Technics SL-PG 490/590, the entry-level players from the Japanese Company (priced around 150 $). It's no mystery, the boards still show the SP-PG 490/590 labels on them.
Then you have what the French engineers have done: added a new board which hosts a dual-mono symmetrical low impedance (750 Ohm) discrete analogue output stage fed by a massive 165 VA toroid and a bunch of small caps (10,000 uF total). That's it.
In Italy we'd call this operation Tweaking d'autore, that is to say, a tweaking session perfomed by a HiFi Company instead of some crazy audiophile.
Then you have the cabinet, exactly the same grossly finished and pretty resonant one used for any other Atoll HiFi component, be it an integrated amp, a preamp or a CD player.
Finally, the remote control: a Technics remote with an Atoll plaque on it :-)
The whole package hits the scales at 7 kgs (that's 14 lbs, more or less) while the size is the usual Atoll one: 44 x 27 x 9 cm.
The Atoll CD 100 makes use of medium-quality gold-plated RCA's, 2 for the analogue output and 1 for the coaxial digital output, while the detachable power cord is again of the Technics kind, that is, the classic, diminutive, ultra-low quality figure-8 plug (no cool IEC receptacles here, sorry).
The output level is easily adjustable from remote, cool if you're a lazy lad, not exactly a must if you're a die-hard audiophile. I, for one, prefer fixed outputs.

我觉得你贴的大概是松下的原型机吧:)
对于如何改的,音响论坛的这贴有说明文字的。


我贴的不是松下原形机. 松下原形是只有一个方牛,加一个黄色解码和模拟输出混合板.

摩机可能不是一步到位的, 也许后来再加一个环牛也为了继续提高性能.

再看看这段话:

The CD transport is a Philips VAM 1201/03 unit, used in many budget Japanese players while the digital circuits and audio boards (including the diminutive power supply transformer) are those of the Technics SL-PG 490/590, the entry-level players from the Japanese Company (priced around 150 $). It's no mystery, the boards still show the SP-PG 490/590 labels on them.

转盘是PHILIPS VAM1201/03, 在很多廉价日本CD机中使用. 数字板和模拟板,带小型变压器, 都是Technics SL-PG 490/590使用的, 这是款入门级日本CD机,价格大约 150美金. 没有秘密.Atoll  板子上仍然有Technics 的标识.

Then you have what the French engineers have done: added a new board which hosts a dual-mono symmetrical low impedance (750 Ohm) discrete analogue output stage fed by a massive 165 VA toroid and a bunch of small caps (10,000 uF total). That's it.
然后你看到法国工程师作了点什么: 加了一块新板, 带有双单声道对称低阻抗模拟输出板, 供电采用一个巨大的 165 VA 的环牛, 和一系列的小电容, 总值是10000 uF,  就这些(改动) .

L 版你贴的大概是新机, 我是从国外网站上看的, 大概已经是老机了, 虽然同型号.

但你看数字板是一样的(下面的黄的) , 那个小方牛,就是原来日本Technics CD机带的.  
Atoll 工程师加了一块绿色的模拟板在上面. 并没有拆除原来的方牛.
我贴的那个只装了一个环牛, 你贴的装了两个,其他大同小异.
