Not at all. I have been very surprised at the hysteric reactions under that thread. I can say that with good probability the ZF will be the best OOTB Sub. It has without doubts a better case, probably better bracelet, dial print is clearly crisper and the bezel and movement is the same. Ok they cost a bit more but it's not a tragedy. Sel gaps are actually minimal and less disturbing than the ones on RXF. Probably Angus will never answer again in that thread and I can't blame him for the kind of reaction certain members had. It could maybe seem a bit conceited to say because I am no expert but it seems that certain guys here lack even the basic knowledge to judge a sub with their eyes and just follow what masses say. Saying that ZF sub is trash is very inexact and will make noobs think that even if it's not true. Costly? Yes. With an average crystal? Maybe. But trash? Not at all.
