OPPO 105D的打磨是美国的MODWRIGHT公司做的。最主要的部分就是把模拟输出的部分改成了胆输出，用了一对6SN7。然后就是用了新的外接胆电源。
详细看这里：
- Total redesign and replacement of single-ended and fully balanced output stage with our own tube analog stage (6SN7 driver tubes).
- External PS (new design) with one rectifier (5AR4, GZ34, 5U4, 5V4 and equivalents) and two voltage regulator tubes (13EM7,12EM7 and suitable subs.)
- ‘Truth’ umbilical of our own design.
- Upgraded Cardas GRFA series RCA’s for stereo outs.
- Upgraded Furutech cryo-treated IEC.
- Highest Quality resistors in key signal path applications.
- All signal wire = 99.9999% pure, cryo-treated solid-core silver wire from Cardas metals.
- Upgrades to internal stock power supplies (Linear power supply replacement for stock SMPSnot included )
- Damping mods for chassis and transport.
- External supply available with optional ‘Hole’ to allow for use of taller, larger diameter tubes other than 5AR4/GZ34 (just ask).
