I'm in a downsized configuration and alternate between Klipsch S4 earbuds at home and Audiotechnica ATH-M50s at work. I have a pair of Beyerdynamic DT770s which are excellent but in storage. My normal desktop setup is an Indeed class D amplifier powering a pair of Emotiva XRM-4.1 monitoring speakers, connected to an Asus Xonar sound card. The speakers are great but I'd like to upgrade the amp and add a dedicated DAC in the future. I've also had a great experience with Emotiva's Airmotiv line for home theater applications.
