I am crazy music and was long in search of a new sound card. Mir is for 2 years no really interesting new development of different manufacturers have noticed until I finally came across a review of Creative Z. What intrigued me was the processor and the new digital / analog converter, which should be much better compared to the Creative Recon. Previously, my favorite, the ASUS Xonar Essence, but will cost 160 euros. I make music themselves (APC40, machine) and am demanding. On the map a Edifier S730 2.1 speaker system depends is suitable for large rooms. I tested with internal sound output, external (Audio Kontrol Native) and give the Z with Toslink cable. The absolute madness against the internal (motherboard) sound output. I had expected that I should listen carefully at different volume levels and settings in order to notice a difference can. Nope, the difference is dramatic, no matter what volume, Toslink cable provided. I will not specify, but suddenly the output of my boxes has doubled, the output quality better by about a factor of 7. The external sound card can not keep up.
I recommend the bulk version without microphone for about 64 euros.
After installation, you should definitely have the latest drivers on the Creative page download.
A nasty case there for, change the audio (RCA) to digital (Toslink cable). Provides absolutely the Device Manager make sure that SPDIF is defined as standard and provides the Windows Mixer and also in the different applications (eg WinAmp, VLC) safe
