Nice write-up as always, I've been anticipating these to release for some time! It's great you were able to compare them to the RE600 which I already have (though I've recabled mine imgur.com/a/1v9kE ) so it was a good basis for reference and seemingly a good contrast. I just received my P1 today, initial impressions are really good so far but I'll need a few more days for them to really sink in. I just had one additional inquiry - if you still have any Linum MMCX cables, have you tried them with these yet? If so, any audible changes over the stock non-mic cable? The stock is very nice build quality and I can certainly live with it if it does 'perform best' but since I wear glasses (and have had experience with a 2-pin Linum in the past on another IEM) I'm spoiled with their high level of comfort. So being mainly a comfort thing, would they be that different otherwise?
