I think the comparison can easily be complicated beyond the possible 6 to 12 models you could compare. First, some streamers perform well in some systems and not so great in others. The person who loves one would not know if it performed well in another system, or even with the change of just one component. Cables make a huge difference, there is a topic, Matrix X-SPDF 2, that has over 2,800 entries and I estimate 20 to 30% deal with cable impact on performance.
You must test the equipment in your system to know for certain. Asking for opinions can help you get started, but real tests are the best avenue for you. Try those with free return trail periods (including cables). The best route, especially if you go through 4 to 6 before making a decision which works for you.
Enjoy your journey, good listening,
