This is a difficult question to give a definitive answer to.
It depends on your system, whether you believe cables make a difference, and if they do, whether the difference is worth paying for (which depends on what your paying for the cable).
I am a big Cardas fan and think they are sweet, natural sounding, musical cables; whereas others find them too warm and not detailed enough. If you are asking my personal (biassed) view, it would be to get them (if at a good price), and sell them on (or return them) if not happy.
The Crosslink is the cheapest of the Cardas range and often sold off the roll and terminated by the dealer....so if this is the case, check it is done well, and that Cardas connectors are used.
