And I am in complete agreement to your reply brunk. Although this is a needed thread is a little to complex I think overall a couple of resisters is all we need in most applications .
However I have just purchased a speaker amp for the sole purpose of using it with headphones , so I have been reading and have bag
Full of ten watt resisters . Lol.
Hehe, you should see my place. I'm up to my ears in resistors and stuff lol. I too am looking to see just how well a single speaker amp can drive my headphones, hence my interest in Robrob's box. However, I'm going to let him be the guinea pig to flesh out any real world issues before I go ahead with it :)
