I prefer the sound of the X1 but when I owned the HD650, I might not have had the proper gear to scale them to the level it deserved. As for the X1, it is very easy to drive.
Yea it should be somewhere here in the topic. Use the search function ;)
I doubt its that bad.
Graphs and real life listening experience are two different domains in my experience. You need other types of measurements also.
I have listened to headphones that by the graph should be bass heavy/light or harsher in the treble that in reality where neither.
I have tried them with Five 9's OCC copper , Four 9's solid silver and currently my favourite is Seven 9's OCC silver plated cryo treated. There is not so much difference between the solid silver and the high purity copper silver plated but the copper multistrand is a much more flexible cable which suits better the rather flimsy 3.5mm jack socket as it has less strain on it.
