Hello,
 
I have few questions about building my first portable amplifier for headphones.
 
I bought O2 from Headnhifi, but it's kinda too big to carry around.
 
Now I am looking for a portable amplifier.
 
Cmoy amplifier looks very good, are there maybe any drill files, because I own one :)
 
Are there some alternatives of Cmoy. Amplifier can be bigger, but not as big as O2.
 
Which one do you recommend ?
 

Best regards,

depends on your application.
 
the mini3 is a good amp and easy to build and has a nice option for lipo battery board.
 
the pimeta is a good amp but will not likely be much smaller than the O2 by the time you add a battery or 2.
 
the carrie is a USB powered amp and not sure if the boards are still available.
 
dont know the a47 and not sure if there are boards available
