I give her 150 dollars. She wants to watch films, video, no more. I don't know the answers to the last two questions. When I know, I'll write here. I looked at a review on the subject amp for beyerdynamic dt 990 pro. I recommend it.

My wife needs a DAC/AMP for DT990 PRO, to rest. She's actively looking for it right now. I don't understand any of this. Maybe someone was looking for a DAC/AMP and you can recommend it?
