I am getting a pair of Beyerdynamic DT880 Pro 250 Ohm cans. I currently connect my cans to a Denon AVR-390 receiver. Do I need an additional amp to drive these properly? I have read a lot of forums, but most people are recommending these portable units or ones that use USB for computers. If so, what is a good amp to get?
I use these for all around listening when my kids go to sleep. Movies, gaming, music, etc. I also own Sennheiser HD598's, but I like a little more bass and I have read these have that. I would prefer to spend in the $100-$300 range on the amp, but I am open to higher end suggestions if you really think it matches well.
I also notice on a lot of the amps that they just have stereo RCA plugs in. If anyone has any tips for configuring the receiver I would appreciate that. Specifically, my question would be if I am running the amp from the stereo lines, how does my receiver know if it should output to my speakers or my cans?
