I have a beyerdynamic DT 990 PRO 250 Ohm headphone and a Logitech Z623 speakerset, which I both want to connect to my PC. For the headphone I want to buy an AMP. Is it possible to plug in both the speakerset and headphone in one amp and plug that AMP in my PC? If so, which AMP would you recommend?
Since the speakers have their own built in amp you can't connect them and headphones to a headphone amp unless it has a line level output.
Using a DAC/headphone amp may be an improvement over just a headphone amp.
