" Hi :
I am trying to get my home audio system into the high end and have purchased a NAD 752 receiver and PSB 4T speakers for starters.(This combination sounds very good).Is it necessary for me to get high end audio interconect cables and high end speaker wire? Secondly I am currently using a Phillips 782C DVD/CD player.
Should I upgrade to a high end CD player, and will I hear any improvement with these or other
Upgrades?

Regards,

Mike"

Absolutely better cables will make a difference. But will spending twice as much on cables give you twice the sound? No, but if your moving to the high end, every little bit makes a difference to the result, better sound. Hope this helps.
