Hi everyone, I have recently bought a second hand pair of 250ohm Beyerdynamic DT990's which I was planning to use with an old Tangent amplifier/DAC, the AMP-50 to be specific. however, the headphone port turned out to be broken(it introduces a hissing-noise, some kind of static) so I have been using it with the onboard-audio on my motherboard(it is a relatively good audio-chip).
I don't know much about audio equipment, but I just need something that can either be ran directly from my PC or through my Tangent amplifier. it being mobile and also possible to be used with my phone is a plus, but not neccesary.
My budget sadly isn't big, I really only want to spend up to $50, if you really think this is not enough just say it, I understand, however, at the moment I won't be spending more on it.
