My D18 arrived on friday in perfect condition. I ordered it during last weekend, so that's an amazingly fast delivery (it comes from hong kong).
The very first impression was very similar with my Essence STX. I have the same OpAmp's (AD8620BR) in my STX, as the D18. So i knew it will fit my taste. And it really does :) it has now roughly 18 to 20 hours of use. it's already a different beast than the STX. i'm looking forward the the 100 hour mark, should be astonishing then. it now is already... 
One thing more to say. I ordered my D18 at GrantFidelity. I got an outstanding customer service, prompt reaction and some nice conversations with Rachel. Again to mention that blazing fast delivery with NO shipping costs from Hon Kong to Switzerland. That's what i call a truely great customer experience.
So i highly recommend GrantFidelity to all of you, you won't be disappointed!
