One more thing about the Oreas: I found the best results to run contrary to what the maker said (as well as MusicDirect). I ended up with them directly under the footers on my gear.
All the advice from both were to experiment placing them directly on the underside (bottom) of the gear. Just moving them a quarter of an inch made a big difference with added this but subtracted that. It was more frustrating under my SACD player than my integrated.
I literally spent hours experimenting and it was always a trade off (with the positives being really nice, sometimes even beguiling, but at too much a detriment to other aspects). So the moral of the story is to try them under the footers.
All the best,
