Which Theta did you buy, the NR or XC? I have three Sigmas now and I always use the XC. I have a Denali and I found when I used the NR with the Denali I lost some "edge" to the music, and what I mean by "edge" was definition, the "decay" of the notes, or the trailing off of the voice. So I went with all XC cables and find the combo of Denali and XC to be a great combo. I have ordered two Theta XC cables to replace to Venom X-EF. All in all, it will be an interesting experiment. I appreciate the insight and remarks, And how did you know I have an eight inch telescope? I am envious that you can see the separation of Saturn's rings. I am just happy to see the rings (or the Red Spot on Jupiter).
