Lot of people buying high end headphones these days end up very disappointed. Simply go through reviews of any online shop that sells headphones. Why do these high end head phones sound bad ? The answer to this is not the headphones themselves but the sources to which people connect these.If you're connecting your high end Sennheiser, Audio Technica, Sony, shure etc to your little ipod and expecting nirvana it's not gonna happen. Most portable music players barring a few i.e. some cowon and sony players are designed to work with very efficient earplugs. They do not have enough power to exploit these high end headphones to their full potential. To get the most out of these high end headphones you need a decent source or an amplifier and offcourse very high quality content. Most people think of any mp3 file with more than 128kps as high end. What you really should look at is the sample rate, listen to stuff that is rippped at 48khz or more sampling rates, flac or audio cd's. The little Cmoy amplifier is literally a Goliath in David form, for what it costs it sounds absolutely amazing. There's a huge market for headphone related stuff and the snake oil bandwagon have joined this. You'll find insanely priced headphone amplifiers with what not. The reality is any decent op-amp even the humble NE5532 can and will drive these headphones quite easily, with silghtly better ones i.e. opa2134 , LME4562 you get amazing sound quality. Chu Moy is a very popular headphone amplifier that’s easy to build yet sounds good, it can be built small enough to fit in a pocket, power supply and all. It’s powerful enough to drive very inefficient headphones to high volumes from even weak sources. CMoy pocket amplifier is an ideal project to get started in audio DIY.
