Our first DIY headphone amplifier MRA received and welcomed.
Thank you once again to accept and support!
This year, we launched the MRB.
Entry-level DIY kit we play a lot. We've been very satisfied or believe won a lot of finished machines?
Now that we have updated leapfrog surprise.
The addition to the fun of DIY. MRB provide a more ideal state, the use of a 9V battery-powered, use LME49720 virtual control, low voltage ripple is relatively stable op amp has a good working condition, in theory, can have a better dynamic, quieter background.
Select the key components in the kit. 1% precision resistors, we have deliberately chosen the ALPS potentiometer. The kit is used to op-amp AD8620/NE5532 ，choose to use the AD8620, because the style of the op amp bias neutral IC, music, vocals and the band's sound in hearing good scalability feel more balanced. You can also change your favorite op amp.
