As I'm sure you have read, Ebay DPAs are hit or miss. I was lucky on mine and love'em.
As far as miniplugs for those go, I gotta admit really liking the tiny right angle plug that sound pros use on their bat boxes. It is a molded connector on an Audio Technica cable. Really lightweight and tiny. Problem is, you can't just solder those. I believe they buy them as an assembly from AT. It would have to be spliced on and I can't say I'm thrilled about that.
Any other tiny RA miniplugs recs?
