When viewing the images it is seen that you have very nice aesthetic stands.
If you want to Upgrade on the mounting of the Devices investigate how the use of a Sub Plinth and Isolation Footers can work for you.
I will suggest the Solid Tech 'Feet of Silence' as I have these and highly rate them.
I have loaned them out as well within my HiFi Group and the reports on the usage are very positive as a result of the impression being made.
