Low watt speaker amp, for power hungry headphones?

post #1 of 2
Thread Starter 

Curious... could I use a pair of these kits in a single ended, output transformer coupled rig for my power hungry K701?

I am more familiar with OP amp DIY, so any general feedback / commentary is appreciated.   Google searching the TDA2003 brings up several discussions and positive commentary on its use as a headphone amp.

 

Some excellent user reviews on the parts-express site... but nothing regarding its use at ~65 ohms.

I have not tried the amp kit you mentioned, but here is some experience/things to watch out for from other low power speaker amps I have built for headphones. 

Noise levels may not be as good as you had hoped for/are used to. 

Gain may not go low enough. 

 

That being said, I would certainly try it. They look like they will be fun for not an insane amount of money. 

If they reallllly suck for headphones you could probably make a guitar amp out of them :)
