Which Node do you have? If it’s an older one, the new Icon Node will be out soon with a much improved DAC. I have a NODE where I have changed out the PSU and use an external DAC via USB. I understand that you may want to save space, but you may find that your Node is an adequate streamer and what will make the biggest difference is spending what funds you have available on a DAC (and decent connecting cable).
That being said, both my audio guys speak highly of the Hifi rose, and I heard it in a system at upscale audio when demoing preamps as well as the house streamer in the showroom of my main dealer that he uses when just working in his office that is to the side of the room (he has better ones but appreciates the ease of operation) and in both cases it sounded really good.
