I take it you like your speakers. I suggest you upgrade your source and also replace the Denon AVR and and possibly the amplifier. That would improve what you are getting from them.
I would start with the purchase of a streamer. The Bluesound Node is within budget. They run $500. The internal DAC is OK, however many replace it with an external DAC of choice. This you could also consider after getting familiar with the Node.
The 1st question I have, are we talking about a 2 channel system for music?. I believe your Denon and Carver amp are meant for theater use. If so, I would consider selling both the Denon and Carver and purchasing an 2-channel integrated amplifier. An integrated is much easier on the budget than separates. However, you could also just replace the Denon with a preamp and continue to use the Carver amp if it works well with your speakers.
There are many threads here on AG concerning streamers, many specific to the Node, as well as integrated amplifiers. I would be inclined to search these threads. I would recommend considering the the used market for amplification.
Good luck in your quest.
