I have a 5.1 home theater and I believe it's "Feather" (i'm not at home), and a Sony Mdrxd100 headset. I used to have a Creative SoundBlaster Live 5.1 sound card, but not anymore, now I used realtek audio device. Both my headset and my home theater are pretty old, but I'm glad to have them, they have great sound and quality, and were affortable by that time I bought them.
When I want to get loud, I plug my computer to my brother's Philips stereo.
