Now, after 1.5 years of use is still far from ideal, everything works, no wear and tear. The decoder station is on my subwoofer wummert orderly, so it will keep something from. It remains at the 5 stars!
------------------
I used to have an X-Fi Titanium after I Windows (and the Creative software) but no longer wanted to do and I have an iMac bought, of course, I wanted to use my Teufel Concept E Magnum PE 5.1.
So I bought the decoder station 5, along with a Toslink cable to the iMac.
I am happy. It requires no software decoder station is easy to use, the connection to the Concept E and the iMac went smoothly.
The most important thing: There are (for me!) No phonetic difference for Titanium. All movies run smoothly with DTS 2.1 Music is stretched to 5.1. By the bass still rattles my lamp on the ceiling, so it's all OK)
The processing seems to be good, but definitely I can not judge, I use the Decoderstation only for 1 day.
First, there's a full 5 stars!
