The leaner sound makes for more detail, take a receiver and turn up the treble you will hear more detail, or take the bass control and turn it down and you will hear more detail.
In my own experience Gaia's feet were installed by my dealer on a visit to my house, played about one minute of music, and said take them off you ruined the balance and the sound. I put the 2 short spikes back on in the front and the taller one in the back and played the same track, he said Well the Gaia cleaned up the sound and I said yes, they do but which one sounds like real music he said Well, the spikes, I said touch the top of the speaker while playing where the tweeter is, I said do you feel vibrations? He said I don't.
Put that money into room acoustic panels. But in the end, if you like the sound that is all that matters so love your Gaia's. But Gaia's do what so many other footers and spikes have done in the past, tighten, clean, and push details more forward. They look different of course as do Townshend Platforms or their Townshend Audio Seismic 'Low frequency' Isolation Pods @$1,000. All will change the sound of anything be it a speaker or an amp etc.
Even different spikes with different materials sound different. I went back to the store with him, and he played the Focal Reference Sopra No.2 speakers for $20,000. They sounded like crap, I looked at Gaia's feet under them, and I said you have the footers that came with the speakers he said, of course, I said put them back on he did, and the speaker improved 100% Still sound tilted on the top and lower treble still not for me but sounded at least more balanced before a B3 organ sounded like a toy playing, and a B3 organ sound is anything but. Once you hear a B3 organ you never forget it is big, full, and warm sounding. Was the organ on many rock records in the 60's and 70's.
