Monoprice 111567 Desktop Headphone Amplifier

welcome to the mana price desktop headphone amplifier he's run about $90 on mana price calm and uh they're pretty well reviewed so I decided to beat the crap out of them with a some heavy-duty testing against i bypassed the DAC in it and went with the Myo DAC through the Lyman and then I bypassed the headphone amplifier by taking my si p2 here and running it from the line out so that I could analyze each one individually so I using the computer would use this is the DAC and the headphone amp and listen and then using the line out to the SP to use this as the amplifier and I can compare which amplifier sounded min on each and they're real close I'm not going to declare a winner on that personal preference I don't know if it's just you know craziness saying that this sounds a little better but we're going to go with with very very very similar amplification levels as you know I'm talking
