Been using one for 2 years now, as I received a beta test set from them previously. The truth cable is, simply put the most detailed cable I have heard. Th resolution is fantastic. To describe what I hear, listening to fine textured with even the DHC Complement 4, the DHC sounds like little fine rocks while the truth sounds like fine sand, not sure if it make sure sense. It is very spacious, but not necessarily the most compared to other top of the line cables (complement 4 sounds really open). It is not really a silver cable and as such has an incredibly impactful yet Super tight bass impact.
The truth copper to my ears actually sounds a tad more open, possibly a tad more detailed and with a more neutral bass, but a tad lusher mids. Overall both are extremely resolving cables, and were what made me believe in cables.
@ExpatinJapan did you get them from Dita directly?
