Current feedback headphone amp

Daft reply springs to mind.

There are many valid reason for headphone requirement, im sure you can think of a few.

I still think your initial post was rather rude to the OP.

If listening to headphones makes you turn it off to do other things, maybe you should learn to listen to the music and not the hifi.
After all that is what it is all about, so if heaphones are the only way, what is the problem?

 

I'm almost ready with amp. It's only cleaning left before I solder the big parts. Before I asked if anybody had any thoughts about the design itself, still no thoughts? Do you like current feedback for instance?

 

I have powered it up now. Seems to work pretty fine, no smoke.

 

I love my little Graham slee amp and 650's not perfect but means I can enjoy stuff that my wife just can't tolerate like hard rock! Weird late night electronica does it for me too.
Headphones and their amps definitly take some getting used to but the benefits reward the patience

 

The amp is up and running.

 

The look like this.

 

I have done some measurements. I can't see any distortion added, < 0.0065%. The hum is comming from my test setup. In real life you can't hear anything.

Pleased to hear you've got this up and running. How does it sound? Hope you're happy with it.

 

How does it sound? In two words: Extremely good!
Am I happy? Yes!
