I just came back from Canjam as well and I agree with the Atlas impressions. It's a Vega on steroids. Bigger, cleaner, harder hitting, larger sound stage, but still smooth as silk.
If the Vega is a nice 32oz porterhouse steak, the Atlas is a 64oz tomahawk ribeye. I think it's a pretty amazing iem for what it is, but it's too much for me.
Build quality is rock solid.
The Comet was a miss for me. For $199, I expected a little more. Knowing what $199 can buy you in the Chi-Fi world, I think these are lacking in clarity and extension on both sides.
It's a very smooth iem, but I think you can do better for the money without looking too hard. Build quality was also amazing on these. I hope he continues with this line and adds a multi-driver BA or a hybrid down the road. I actually like the housing on these iems.
