Cardas cables are the warmest in the least expensive category and become less so in each level up. That is by design. Yes Cardas Clear would be a good choice paired with a Luxman. Which is best will be a call depending on your tastes. I would not consider any of Cardas to be warm and cuddly. They are all seriously good… but with a construction favoring different kinds of equipment. As far as I know this is the only company taking such a pragmatic approach.
