These are my upgrades during the past 2 years. I spend much time in search of the sound that I like. I am after high c/p solutions. I have experimented a lot with various materials used for 灌沙線, fitting 牆蘇 & 加環牛 for my DacMagic. 派拉利 is my favorite DIY pc; there are many variations to manipulate it for better sounds. All these was done due to one simple reason. That is to maximize the performance of the equipment that I have on hand.
I also had Onkyo 803 but lost the pic. That amp sounded terrible. So I gave it to a friend.
I recently acquired a 2nd hand DacMagic: 分析力高, 清晰 & 背景靜. The original 牛牛 was not audio grade. So I decided to DIY a 環牛. I used much of the material I found around my home to complete this project, so 老板 wouldn't complain about unwise spending.
A ching explained: if you connect the input from the AC mains then it will output 12 volts AC. The diodes inside the DAC will then convert the AC 12 volts into DC 12 volts before the regulating stage. All you need to do is housing the transformer into a box and connecting the mains to the input wires, but you also need to join the output wires with the appropriate cable and mini jack connector to the input of the DAC itself. Because the transformer can output 2 x 12 volts, so you only use one of its outputs.
After upgrading to a 環牛, it almost sounds like I changed to a new DAC! Female voices are more emotional than b4. The guitar strings are more detailed and with longer 尾音. Bass is better than my previous V-DAC.
I have DIY many pc with 派拉利 1.5mm b4. This is the 1st time I used 派拉利 1.5mm with DAC. I found the performance very comfortable to the ears. 派拉利 1.5mm surely is an amazing cable! 加灌沙, the results are even more pleasing. There is no negative comments about the 灌沙線. The 1st thing I noticed was the improvement in bass. The sound stage is wider & deeper. Guitar strings are better controlled.
電流多震動, so added 石英沙 inside the 威化餅罐 and 個罐底加了釘.

Marantz MM8003 is lacking in power. Cayin 1205.1A is more powerful with a tend of harshness, great for action movies.
