I have an original Creative Soundblaster Audigy sound card and Onboard Realtek audio in my current desktop. I have a set of Bose headphones which I really like, but I'm wondering what my best setup would be? The Realtek audio is: Realtek ALC885 High Definition audio CODEC 8-channel audio output DAC SNR/ADC SNR of 106dB/101dB Full-rate lossless content protection technology Optical S/PDIF-out and coaxial RCA S/PDIF-out interfaces I've tried out both and they seem to sound the same to me. I use my computer for everything: music, movies, games. What would be the best setup with my current hardware?
