TH900 is papa Bush, 600 is son Bush
That's a little harsh, they can't be that bad.
Yeah im kinda scared away from TH900 bcuz of their treble.
I've chosen the Sennheiser HD 600 as my introduction but choosing a DAC/AMP is abit confusing and seems quiet hard to drive (spikes all the way to 550 ohms).
I've noticed that people seem to like to pair tube amps with the hd600 but they dont really appeal to me because they can introduce disortion and colour into the sound and seem inferior to solid state from a glance imo. But if u can change my mind I might be willing to consider them.
