I used a Denon 1650 for years. I still have it upstairs so I have something I can use in a pinch. It has not been turned on for at least 5 years. I think you will be amazed at how far digital has come, provided that you are able to hear some of the really good stuff that is available now. For the price of a used Cary 303T, I would suggest you also consider a new or used ModWright Sony or Oppo.
I've heard a couple of the Esoteric players. They are good, but I will stick with my ModWright Sony.
