Thanks buddies.
I'm glad the CS4's are 16Bit as well.
I will try one saber than, before i'll go for a Vader ANH conversion, just to see waht it does.
A CF board probably wont fit in a K4 either, so a CS will be the way to go.
The seller makes his sabers very loud, but he also made some of my CF sabers very loud, so there still will be a difference, but the 1 accucell solution gives the sound more resonance, which hopefully will compensation it a bit?
