That's what I thought too...but this one seems to use a different chip...I don't think that chip (KA2209 IC FROM SAMSUNG) is an opamp...

I can't seem to find this chip used in any headphone amps...any builders here know if this is a good amp to use for headphones?

KA2209 and TDA2822 are interchageable... but it seems more people are using TDA2822.. its slightly cheaper than cmoy.. cost me around $15?

OH YAH!!! this is an amp for dark sounding headphones!!!
