THE ORRONOCO AUDIO DIY

I am enjoying my life recently by listening music on this Tripath DAC amplifier. I am not doing any upgrade on it just because I am satisfy with this tiny amp from  tripath . Then from my last upgrade  here , I combine this little amp with simple DAC circuit from TDA1543. It sound wonderful. I listen to my music albums collection again and again. Until one day, I notice something went wrong. The sound should be more lively especially on the lower octave. The bass shy and this is not right.

DIY Schumman generator is inspired by Acoustic Revive RR-77 reviewed by  6moons . Surprisingly, the components to make is simple, cheap and easy to obtain. The case that I using here is a gift from my colleague few years ago. It is used to be a cigarette box and it is made from solid wood.
