Dared MP5

ok this is not really a review, more like an impression. i havent spent that much time with it, its not mine, its my friend's. im only writing this because theres no one else reviewing it. i listened to it a while ago, and at that time i only had an ipod classic with a fiio e17 strapped onto it and headphone used was my beyerdynamic dt990 pro 250ohm, cable was a cheap 10 bucks radioshack cable. using the mp5 makes the sound seem warmer and less fatiguing but i dont know if its my electricity outlet or something, it was very noisy. just using the e17 gave a much cleaner sound and had blacker background, i ultimately prefer the sound of just the e17 more. take my impression with a grain of salt though because of double amping, ipod dac is nothing high end, cable was only a cheap 10 bucks cable... so many things were not optimal... but i also have to add, later when i had my ibasso dx100 and used it (when my dx100 was still working) via lineout, the noise was still there, i dont know about using another wall outlet though since i didnt move the amp to other place to try out, hopefully this is not the amps problem. im going to rate the amps overall rating (otherwise i cant submit this) with my own experience but again it barely means anything as so many things can go wrong instead of the amp itself.
