Hey guys, I am currently using a pair of Beyerdynamic DT990's + Xonar Essence STX with swapped op Amps. I have been looking at getting a Burson Audio HA-160 to amplify them. However I have also been harking back to my Old Audio Technica Ad-700's and just how comfortable they were. I know they don't sound as good as My DT-990's so I would probably get an adh-900 or 1000 model. What I would like to know is, is there any point buying an external Amp for the Audio Technica range as they are so easy to run?
Are gains in Audio quality when swapping to a really good amp greater for a higher impedence model?
