看來這個世界太過熱心是多餘的
畫跟電子產品不一樣，電子產品用看的，可以看出
一些東西，隔行如隔山，所以有的東西很難說的清楚
以下是網站的說明，裡面有詳細的資料，根本沒用PCM63
我不知道JAZZ說的那些數據是那生出來的，數據差的
很離譜，言盡於些，我不會再回了，各位看看就好

The DAC Kit 1.1 is a stereo digital to analogue converter using Audio Note 1 X over sampling techniques. This configuration in our opinion has proven to be musically superior to other over sampling methods. The kit uses the well proven Crystal CS8412CP input receiver, and the DAC chip is the Analog Devices 18 bit AD1865N. The tube output stage uses a single 12AU7A / ECC82 as a common cathode amplifier which provides voltage gain to allow the Dac Kit 1.1 to be used with any active preamplifier, and some passive preamplifiers.

The DAC Kit 1.1 is housed in a full sized steel chassis (11 3/4W x 5 1/4H x 15 3/4D) finished in black textured powder coat, and a 3/16" brushed aluminum face plate, anodized natural colour, with a satin finish. The DAC Kit 1.1 is shipped with a pre-assembled and tested digital PCB, and all other parts required to complete the kit. A comprehensive assembly manual is included with step by step instructions.
