I've got them between my pre-amp and power amp on the recommendation of the Leema Acoustics rep. He reckoned it was the "minimum standard" cable to put between their components. I haven't auditioned any other cables (more due to time constraints than anything else!) so all I can say is that I am very happy with the combination.
I think that your best bet is to try and find a dealer who'll let you borrow some to see if it works for your system. It's the only way that you'll know whether it's good for you.
