I must also agree with the What Hi Fi review. These, to my ears sound like top quality cables with mounds of effortless detail throughout the frequency spectrum.

In the context of an all Rega system however, I found that these cables do seem to paint a kind of two dimensional stage. What I mean is that while instruments appear to be focused and in place between the speakers, there's no portrayal of their position behind or in front of the speakers. There's no stage depth. Having said all that, I am sure given right system the Crystal Cu's would sing a lovely song.

Id have to wholeheartedly agree with the review. Reveals bags of detail and texture. Lots of energy and dynmaics too.
