You can get a much better DAC than your present one if you go for recent technology. For me it would be a SimAudio Moon 100D or for 3 times as much, the 300D. The Calyx DACs are nice too.
You can get a better transport than your Rotel's, and if I went that way I would look for a used Esoteric. Even the older ones can still be repaired and the prices are good. However a lot of us are using computers as transports and if you're comfortable with that kind of setup, you can get sound that rivals the very best of them for a much lower price.
