I am new to the headphone side of life and my first pair of phones are Fostex t50rp's
mod by Mayflower and a Matrix amp. Well I should have listened to my little voice,
I really want a tube amp so I have been agonizing over the 600/650 choice and I am
leaning toward the 600. With that said I am wondering whether or not you can reach a
point where the headphones disappear as in my 2 channel speaker system?
