Sims Navcom Isolation Pucks vs. SQ Isol-Pads

I am looking to apply some vibration isolation to my audio components -- CDP, Integrated Amp, DAC. As I am only starting in this area --- and an entire new rack or shelf is not an option -- I am looking for feedback on these two items.

My equipment is all solid state -- not tubes. Currently housed in a custom wood cabinet. However, some vibration in room from HVAC/Water heater when running.

Any thoughts regarding these 2 options - or others in the same cost range would be appreciated.
