Yes and no. They are only 70 ohms, so they could be driven fairly easy with a laptop or device. However, since it's super detail and articulation that these deliver (and you want), they are very critical of what you feed them. This includes the bit rate of the music, how well it was mastered, your DAC and your amp.
Having said that, I started out with my SA5000 with a little $50 Cmoy amp and upgraded later. It has the power the headphones need. But it will not make them sound as smooth and delicious as they are capable of. So, if you are wanting to work with your headphones after purchase, the SA5000 has a lot of room to grow with hardware upgrades. Get a cheap amp now and go from there. If you don't want to ever spend the money on the gear, you may want to look elsewhere. But elsewhere, you just won't find this level of detail and awesomeness until you step up to a headphone that is much more expensive... in my opinion.... and in many other's opinion.
