Count me in the club too. I was virgin just a few days ago. After a long research I jumped on board, why not get a classic to enjoy in the autumn. Still burning them in (15 hours ), but sound way better than my cheaper Grado 125i allready. Agree on all the positve that have been said about them. Maybe the sound is a little too warm and dark with my Musical Fidelity X-Can V8P tube amp, but the X-can drive them like a dream. We will see the next 100-200 hours what will change. If Im not totally happy my hand will be forced to get the Musical Fidelity M1 HPA (pure class A amp) in october. Heard it´s a good match. I will do everything to make my HD650 feel at home and sing like a mockingbird
