Definitely my home rig. My portable rig doesn't see that much use. My work environment is too dusty to risk using my portable rig, so it gets used while biking and walking the pooch, or on the long walks I like to take on the beach in the early evenings.
I find that I like the ease of just plugging my Denon AH-D1001's straight into my iPod classic. I'm able to separate critical listening for convenience in my portable rig.
At home it's quite a different matter, and I'm getting really itchy to have my new DAC and amp that are being built for me. I listen to music a great deal at home, and I want it to sound as good as I can get it. I'm hoping my new upgrades will keep me smiling for a long time.
