is anybody routinely using a truly portable amp with the dx90? i have an ifi idsd micro, which sounds great from the dx90's line out [i prefer the dx90 dac stage to the ifi's], but the micro is hardly something you'd want to carry around. so is there a smaller, truly portable amp that anyone is using regularly and getting better quality sound?
I stack it with C5.
it measures at 136 * 63 * 15 (mm), slightly shorter and thinner than mirco
