Big 7 DAC 大七解碼器

在亚洲只引进胆整流版。Big7大七和Golden Gate金门都不是R2R的。请注意。单端69999元,平衡89999元。

关键词: LampizatOr、DSD、 直热三级管、纯铜电容


We give to every DAC, especially the Big7, the best parts that we consider sanely priced.
我们给每一款DAC,特别是Big7,理智考虑价格下的最佳零件。(说人话就是堆料)。

The Big Seven is an evolution of Level 7 – we put in one huge box the whole L7 and then some.
Big 7从Level 7进化而来。我们把整套Level 7装进一个大盒子里。(Level 7原来是分体的)。

We feel there is an advantage to put the Level 7 in one box because grounds become shorter, power delivery is more immediate and there is possibility to put more power supplies separately: we have about 20 in total in Big Seven compared to 9 in Level 7. Also we can use bigger rectifier tubes like 5c3s and Bendix 5U4R or even Shuguang 274B or Emission LABS 5U4R.
我们认为把Level 7放在一个盒子里有很大的好处。地线更短,功率传递更直接,而且可以把电源组件更加复杂化。结果就是从Level 7的9路供电变成现在的20路供电。我们还可以用更大的整流胆管,巴拉巴拉巴拉。。。

This DAC will have as standard (no price premium):
这个DAC的标准配置(基本价格)

• Output capacitors  Jupiter Copper Wax – the best coppers in the world in our opinion.
输出电容Jupiter Cooper Wax。我们心中的宇宙最佳铜电容。

• Tubes: Standard Psvane 101D, optionally Emmission Labs 45 or KR45 or 300B UK Design Psvane
放大胆管:巴拉巴拉巴拉型号

• Rectifiers 5C3S from USSR or 274B from Shuguang. Optional Emission Labs 5u4g
整流胆管:巴拉巴拉巴拉型号

• PCM DAC 384 kHz, optionally discrete resistor ladder chip-less PCM
可选R2R分立电阻阶梯式解码

• USB up to 32 bit/384 kHz

• DSD128/64 engine (the one that made us famous), optionally 256x
DSD64/128支持,DSD256可选

Paid options are:
可选的(当然是付费)

• Volume control with a remote
• DSD 256 or 512 engine
音量遥控,DSD256或DSD512

• Balanced topology
平衡版

• The tube rolling possibility allows to use 101D, 45, 245UX, 2A3 – with a switch selector of heater voltage.
支持一些胆管倒置 ,有灯丝电压切换开关。


Let’s summarize the Big Seven build principles:
总结一下吧

• DHT triodes in single ended anode follower configuration as Lampizator signal tubes (45 or 2A3 or 101D)
直热三极管,单端阳极跟随器,配置LampizatOr信号放大胆管(45 or 2A3 or 101D)

• You have a selector switch to choose three tube schemes (2A3/45/101D) but you get only one chosen tube pair. Tube rolling is entirely on you.
您可以在以上三种胆管先一种。正着装还是倒着装随您喜欢。

• Only one amplification stages in the whole DAC
整台DAC只有一级放大

• Only one capacitor in series with the sound in the whole DAC (two for volume control version) and we give you worlds best capacitor.
声音回路中只有一只电容(能调音量的版本是2只), 我们给你世界上最好的电容。

• Duelund Cast Copper caps or Jupiter Copper Wax exclusively
Duelund Cast铜电容or Jupiter Wax铜电容,独一无二滴

• Silver wire in teflon insulation point to point 3-D connection technique
特福龙皮的银线,搭棚焊接

• Tube power supply with tube rectification based on the best 5C3S /5U4G / GZ34 / 274B vacuum diodes
胆整流给胆管供电(吃腰子补肾的赶脚)

• MKP foil caps of gigantic size (total of 290 uF MKP capacitance) replace most of the PSU reservoir electrolytes
巨大的290uF MKP电容用在电源模组中,取代高压电解。

• Separate transformer windings for tube circuit, separate transformer for digital part, separate secondary windings for every task
独立绕组给胆管电路,独立变压器给数字部分,每个任务单独分配独立绕组。

• Our top digital section with current-output DAC converters
自有数字组件包含电流输出方式的DA转换器

• DSD based on our best concept of using un-manipulated, filtered, raw, native datastream as signal.
DSD基于我们的最佳理念巴啦巴啦巴啦。。。
