Unlike some, I have seen the benefit of interconnects and speaker cable upgrades, both on purchased and my own home made silver cables. I have been skeptical about power cords. I have been tempted to try, but it will probably be with a cable I build before I sink any money in it. I do know that parts Connexion has some DH Labs cable they wil build on sale and also the the people that made the highly rated Ah! TJoeb CD player are now selling cables through Upscale Audio who is a good guy to do business with. Those are lower cost options, I would not throw a lot of bucks at this until you experimented.
