Received my F3 the other day - thanks for delaying it an extra day to Fedex.
I left the design up to Custom Art and holy crap, what I got was more than I expected. They simply look stunning. Took some pictures today as it was a little sunny outside, but only had my iPhone, so don't mind the quality (the pictures don't quite do them justice). I'll take some new ones with my Nikon gear another day...
I think I'll call this design for "Lost in Space" or something.
After having used them for a few days now, I really do enjoy them. I've otherwise primarily been enjoying my SE5U for the last couple of months, so it was interesting to try something with a (very) different and brighter signature. But they actually supplement them quite well - much better than I expected. The SE5U still has a little better "stage" and seperation (and 3 times the price), but the F3 brings out things I've never noticed before in tracks I've heard hundreds of times, and the bass and highs so nicely tuned. They are very enjoyable and my favourite Custom Arts so far (having tried most of their line-up).
I'll be using them mostly for "traveling", so right now they are paired with the AAW Capri cable/dac, but I did most of the listening so far with the Mojo.
They do sound as good as they look.
I'm impressed. Thanks Custom Art.
