[hello im sean]

Hi, i was wondering if i should go all tube for the 900 or hybrid? i've always had a thing for the diy bijou.. but if the low impedance of the 900 wont cooperate i could fine a decent hybrid im sure.  would a little dot I+ do a good enough job? or maybe a mini-max? i'm really not sure how much quality amping the ultrasones need, enlightenment please
