Oh Gawd... Why would you want to? Your ARC preamp is a wonderful piece and the Denon is Best Buy grade. If you need a phono stage, there are any number of affordable pieces of a similar level of quality. I'm very fond of what you can get at http://tubes4hifi.com/ because it's a very good value. You can even save some money if you build it from one of their kits. They can also build it for you for a modest amount extra.
