THE ORRONOCO AUDIO DIY

I still owned several iPod model and they are become my audio portable since 2 decades ago. Those iPod sounds very good considerably to today standard. Just plug the 30 pin to audio line out adapter to the amplifier and it sound at it is optimum performance. Just in case you forget, about 10 years ago, iPod and DIY Cmoy amplifier become very popular among portable audiophile for on the go setup. Sadly most of the 30 pins to audio line out adapter is only provided by third party manufacture. The best one that I can recommend is from Fiio. At that time, Fiio released several model 30 pin to line out adapter but none of those Fiio adapter product are still available right now. I still have one and it still working flawlessly until now. So if you want to find the same function as Fiio audio line out adapter but better, then go through this Apple original product. This is component AV cable made by Apple for iPod accessories back then.

Using a Cmoy amplifier is actually good enough to deliver a good sound through a headphones. Building Cmoy amplifier is basically easy and cheap. For the comparison, I have been using Schiit Magni headphones amplifier and Cmoy amplifier sound quality is comparable The designer of this Cmoy amplifier is based on one person name Chu Moy and the amplifier layout is basically an op-amp gain which very simple and not too much parts involved. The standard op-amps for Cmoy amplifier is using NJM4560 that can deliver up to 70mA of current with minimum impedance output is 150 ohm. But how it sound if I compare to the others op-amps such as LME49720 or NE5532?

My previous built the Gainclone LM3886 amplifier  here is become my main amplifier in home audio setup. I was built this amplifier in hurry so I can start to evaluate the sound quality and testing the sound difference with many kind of DAC. Yet the built result is not very neat. The cables are all around inside the amplifier and need to be tidy up. That is why in this weekend I have a chance to doing re-cabling, also try different approach in the volume control circuit by using the not-popular shunt-volume control instead of common resistance divider volume control. This shunt-volume control using standard potentiometer is the cheaper approach compares to the more expensive ladder type volume control.
