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

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
