It will be a few weeks before any of us have the final custom product, so if you wanted to be cautious, and why not, I'd wait until then. I don't think iems can replace a good home set-up, but I also think my UE11s are better than many mediocre headphones, and I liked the universal 13s better than my custom 11s. I know of at least 6 head-casers that are getting them (me, tyrion, jp11801, vpi, edwood, iron dreamer) and I don't think any of us are going to say they're better than they may be or visa versa. Who else here is getting a pair?
