I am planning my future home rig based around the HD650 that i will be putting together over the next few years(student's budget here). I have (almost) decided on getting the Yulong D100 DAC to go with the HD650 balanced. What i am not very sure of is the amp. I have been looking at a balanced beta22. However, i have not decided yet. Here are my questions:
1) Do the HD650 pair better with a tube amp, or a solid state amp?
2) For a price of $2.5k, what are the options, both tube and solid state, that i should be looking at?
