Stone Age Three point zero

Perhaps, the appearance of DAC which adheres to the playback of normal CD to here, exhausts the 贅 probably is unprecedented.

With the appearance of Three point zero, the inevitability which already inquires about the analog record was gone.

First please view the flow of signal processing of Three point zero.

Digital input
↓
Pulse transformer
↓
Tranceiver IC (ST micro electronics ST490A)
↓
Digital audio interface transmitter (CS8412-IS)
↓
DA converter (Philips TDA1541)
↓
IV conversion (バーブラウン OPA627BP)

Analog conversion (バーブラウン OPA627BP)

The power source supply to the above-mentioned device, altogether you do not use 3 terminal regulator which generates noise, you do with the complete discrete power source 10, shunt regulator TL431 is used quite the good quality, you operate all devices with the power source environment which at the same time is stabilized.

Even the printed circuit board you do not use for the circuit module which becomes the nucleus. In 1,5mm thick epoxy make "bull's eye baseplate" all parts are mounted, the part is connected with aerial wiring. Rather than passing by pattern wiring which is dumped to the baseplate the coming out of the vibration was fast markedly, 50% could reduce also solder place.

It could not remove from CD the other converter by any means, "it is vivid", the "stirring impression", being to remove due to this circuit module, it does Three point zero.

And, Three point zero semipermanent life and the フ fat ｣ 襯 爛 ash 鵐 妊 鵐 machine 爾 village 澆 pouch which has the highest sound quality is only DAC which the ｮ is done softly. You do not use the electrolytic condenser altogether. It is DAC which has the high speed low inertia power source which tops the group small capacity 330 μ F (with being size about of the can cola) 4 film condensers and recovery time = 18 with the super high-speed diode, nano- second.

As for power transformer the R core trance of 70VA 1 basis you use for also 1 basis, and IV conversion and the analog section for the digital section, remove mutual interference.

As for the power transformer and enormous condenser block 2, "Triangle ' s Nest Structure (TNS structure)... as for details penetrating the main chassis please refer to One point zero" due to, with 3 point feet of the respective aluminum make, it becomes independent in the installation stand. To the fact that it is locked to the main chassis which was painted "intelligent black" circuit module and the input/output terminal, private power source module for the indicator light, is just this to that.

The input/output cable has used Stern crank make Ephemera (details please refer to One point zero). High speed the circuit, high speed obtaining the chassis and the internal wiring material, shows the real value for the first time.

Contents of Three point zero are not the odd maniacs reach. It is the work where deep attachment of the designer of Stone Age that "we would like to inquire about CD with the sound which it can pass away", bears.

Three point zero, being simple, if it combines with good quality transport, it is not defeated to the analog record, "it is vivid", with the "stirring impression" is pulled out from CD. And in the reproducibility of the delicate nuance and the accuracy of expression, the analog record is surpassed.
