As I thought, a few different methods are used. The points/spiking seem to be a common method.
I've decided to start with my speakers first, then my amp. The speakers are EW Andra, the original model. Using their stock spikes, things are a bit loose, but when I took off the spikes, and left the threaded post on, things seemed more solid and clear. When I removed the threaded posts that the spikes screw into, putting the flat bottom of the speaker directly on the floor, things became less defined and a bit muddy.
So, I will try Audio Points, and if success, I will upgrade to Sistrum platforms under them as well. If neither of these work well for me, I may try sound anchors under them.
I believe the Audio points and sistrum have a money back guarantee, so I will try that first. Perhaps sound anchors do as well - I need to check.
At any rate, I think I need to finalize the speakers first. Once that is done, given the success or lack thereof of the Audio Points/Sistrum or Sound Anchors on the speakers, I will try those same options on the Omega amp.
Thanks,
Jim
