Power cord suggestions to improve cd playback


Presently I have a Denon 2800 cdp feeding a Denon 4802. Speakers are B&W N805. I am in the process of buying separate amplifier and will use the 4802 as my pre. Without buying a dedicated cdp, will power cord upgrade make any appreciable difference with my set-up? I have heard Analysis Plus makes some solid performing cables/cords. Is this true?
Thanks in advace for your comments!

A friend of mine uses a Denon 2800 dvd player for his source unit for 2 channel and for HT. I took a couple of my power cables over and he thought they were awesome. I use Virtual Image Pile Driver power cables. This friend of mine uses a Denon 2800(source), Denon AVR-3300(pre-amp), and Antique Sound Labs Wave 8's, his IC's are the AR Pro cables that everyone raved about, his speaker cables are some older Tara Labs Reference Gen. 2000 that I sold him a couple of years ago, and Roman Audio speakers. We placed a single Virtual Image Pile Driver power cable on his 2800 and he was astounded by the improvements. I use all Virtual Image power cables and interconnects on my 2 channel system and power cables on my wife's HT system. If you would like to try the V.I. cables, you can e-mail Al, owner of Virtual Image, at virtualimage@juno.com. He has a 30 day return policy on all of his standard cables, which for a Pile Driver is a six foot cable with a 15 amp IEC, which has an introductory price of $400. He also makes another power cable he calls Sledgehammer. It is cheaper than the Pile Driver ($200), and gives you about 90% of the performance of the Pile Driver. Also, if you are interested, e-mail Al and ask him if he has any demo cables that he would be willing to discount for you, every now and then he gets some. Anyway, if you have any questions about the V.I. power cables and/or interconnects, based on my experience with them, feel free to e-mail me or search the forum archives for "Virtual Image".
Most of the Electroglides are excellent for digital. Also very good at at better price is the Shunyata Black Mamba v1 or v2.

True, they are a bit pricey, but the Harmonix Studio Master power cords are wonderful. Have never heard the Elrods, but a couple of "golden earred" audiophools, I know, changed from Elrods to the Harmonix Studio Masters. That was motivation, enough, to give them a whirl. The icing on the cake for electric nirvana. UNBELIEVABLE!! peace, warren
