Having reviewed the Lab 1 myself, I am in agreement with many of your observations.  Hope you enjoy it. 

I'm not sure I buy the value proposition, that high rating should be lower. £1299 without a replaceable cable and only two balanced armature drivers is pretty insane. Maybe you are swimming in a lot more money than most of us? I'd like more detail about the sound. The descriptions here give me very little idea of how it sounds and there are no comparisons with non FAD IEMs beyond saying that here are two other TOTL IEMs and they also sound fantastic.
