Increasing detail and resolution will improve imaging. Increased detail provides better imaging cues, more air around images. An effective way to improve detail and resolution is to isolate the speakers and components. The best way to isolate is by using springs.
For decades my speakers sat on spikes. I knew spikes improved the sound over the speakers resting directly on the floor. Then a few years back I got the idea to build some spring platforms for my speakers. The improvement in sound and detail blew me away. Eventually I bought the Isoacoustic footers. They sounded a bit better than my self made spring platforms and were also much easier to use. Wrestling 130 lb speakers onto my self made spring platforms was a bit tricky. I use Isoacoustic footers on my current 238 lb speakers and they are clearly superior to the factory supplied spikes. The subwoofers in my HT setup now use my self made spring platforms and they sound great. Having the subs isolated from the floor eliminates all muddiness in the bass.
With that success I tried isolating my components with springs. I found that it is better to isolate the shelves with the springs vs. putting the components directly on the springs. Isolate the shelves and then place the components on those shelves and use your damping of choice between the component and shelf. The ideal isolation is to have the shelf/component combo resonate at around 3 Hz. That can be difficult to achieve sitting on compression springs; but I find that below 7 Hz works very well. I have thought about building shelves that hang on extension springs. It would be much easier to achieve 3 Hz but my system sounds so good right now I have no motivation to tinker any further. Maybe later, perhaps. Although I have already seen a couple of examples of racks using shelves suspended on springs.
I gained so much detail that I found it distracting at first. It took away from the music. I almost wanted to go back but it is like letting the genie out of the bottle. Fortunately, in time I grew accustomed to the added detail and resolution and was back to enjoying the music even more with the improved imaging. It's quite a thrill listening to a Chorale piece and hearing each individual voice across the sound stage vs. a cloud of voices.
