I actually have bought something from Tran on head-fi. A CFA-3 build. It is working fine so far. I sent some pictures of the internals to Kerry when i first got it, and it didn't seem to raise any red flags. I also have one of his KGSSHV Carbon builds he sold on ebay. It does some crazy inrush that my lights in my room dim a second when it turns on, but works well otherwise. I haven't used his carbon enough to know if it will fail, as i was lucky enough to get one of Kerry's T2s.
Also forgot to add, i have a SUSY Dynahi from Tran that is also working well. Haven't used in a little while though
If @Kerryis reading this, i'm waiting to get one of your CFA3's haha.
