I had the Gaia 1’s under my Sopra 2 speakers and was quite impressed with them. Then one of threads talked about the Townshend podiums. I contacted them via email (in England) and they responded the next day.
I ordered them and once installed I couldn’t believe the improvement in sound staging, frequency response, etc. And, I thought the Gaia’s were good! I was sold on them.
BTW, when I removed the Sopra’s spikes they sat perfectly on the podiums and in my opinion didn’t raise them anymore than they were with the spikes installed. For sure they were shorter than with the Gaia’ 1’s. And you can adjust the height, rake etc.
I ended up installing the Gaia’s under my JL F-113 subs.
