I use the device coupled with a 11 year old magnavox cd player. It has smoothed out all the rough edges and added the missing detail. I have used it with a very cheap magnavox DVD player and loved it. I have found the cheaper the player the better the x-10 sounded. I tried it in my main system on the output side of my CAL Alpha/Delta. It sounded muddy and masked the inter detail. Good luck
