Are you in the U.S.? My personal experience has been that the U.S. distributor for Arcam, Audiophile Systems, Ltd., are excellent folks and are happy to assist with issues involving their product lines.
On two different occassions, ASL Group repaired used items that I had sold here on AudiogoN. They were under no obligation to do so as the items were used, without warranty and it was not for the original owner.
I would check with ASL Group first to determine if the sound is normal and if it is not, see if they can assist you with the repair.
BTW, I have heard of other CD players clicking under certain circumstances. It might be normal. But, check with the folks at ASL Group to get verification and assistance.
