best interconnects and power cables for Ayre

Before you worry about cables you've got to fix your source. As noted above, it would be helpful to know your speakers as well.

Cable selection is a a very subjective issue. Ayre does use Cardas cables to voice their electronics. I have found that there may be significant differencs in cable performance, even within the same manufacturer's range. All Ayre components are of a balanced design, so experiment with differnt XLR cables, starting with different Cardas models.

Thanks. I have Merlin speakers. I do use the D1 for video as well, but I agree it can be bettered. What about power cables ?

Perhaps the D1 can be bettered, but I think it is pretty darn good RedBook player; especially in the context of an all Ayre system. I would certainly audition the CX5 before assuming it will be an improvement for you and your ears. I would think the Cardas GR could not possibly casue fatigue, but they are a bit pricey.

The D1 - especially if it has been modified to the last iteration (it isn't currently being made any more) is a wonderful player. The C5xe however is better (not slightly) with Redbook CD's however, it also plays SACD and DVD audio which the D1 doesn't. Listening to the Tilson-Thomas Mahler SACD discs wants for nothing that I can hear. I have both units. In my all Ayre system, anything made by Cardas ruins the sound.
