They are installed. Before and after I recorded a selection of my 'review' song-snippets. I made a simple video (as in, it has no distractions) where I switch every 15 seconds between the situation before and after. The video can be
downloaded from here.
My microphone, which I normally only use for voice chat with friends, isn't up to the task. It introduces a lot of noise and doesn't capture the real situation well. But with nothing better at hand, it had to do. Just use the video to (try to) hear the changes in sound. But please don't think that it's even close to the sound quality that I myself hear. That would be embarrassing.
I have filtered the microphone induced noise out a bit by creating a noise profile of my microphone and applying the same noise filter on both recordings. Using the video software I chopped up the recordings into 15 second tracks and added text to let you know when it's using spikes or the GAIA III's. For the rest it's basically a black canvas, so that you can concentrate on the sound.
My conclusion so far is that there is a noticeable change, bigger than I am able to hear back in the video. I would describe it as
cleaner, clearer and crisper.
Also noticeable was that the bass is less prominently present then before, but is also better defined.
The GAIA's, still sitting on the slab of granite, do a better job than the spikes. I will need to get the measurement mic out again to adjust the room equalisation profiles...
What I also like is that the GAIA's have suction cup feet. So on the granite slab their is no way that I can bump them of the slab. They're stuck to it quite firmly. With the spikes I had to be a bit careful about bumping into them.
FYI:
Audio captures with
Auna Mic-900 USB microphone and
Audacity as audio software. Noise filter applied with Audacity. Video created with the free version of
DaVinci Resolve 15. Nothing else was changed apart from the spikes. All placements before and after are the same.
