Gintaras brings up a good point though, may as well just pay once and be happy, because often you'll spend the amount of a 1plus2 unit in a few months here in dribbles, without really obtaining the same sound the Tralucents can reproduce. I'm glad you got to hear them....
I also agree Gintaras has a point and wish I would have done this right away as well (after I purchased my Tera player few knowledgeable members recommended 1plus2 as perfect IEM for Tera but at that time I was skeptical of the price and decided to try few cheaper alternatives first).
Currently I'm waiting for 1plus2 to be delivered and still using RE-600 (which I do like but there is still a noticeable gap in SQ between it and my Porta Pro's which sound incredible paired with Tera - I'm hoping 1plus2 can close the SQ gap for those situations when open phones are not possible).
So in retrospect if 1plus2 ends up sounding as good as quite a few owners/reviewers have reported I will feel like I should have gone to it right away and be done with it (like I did with Tera player which is without doubt the end game perfect player for me).
