IsoAcoustics GAIA

I tried the Gaia  feet on a pair of B&W speakers and it made a huge improvement-much better imaging and coherence overall.  

I then moved to Magico speakers and I didn't like what the Gaia feet brought to the sound- it softened the transients too much and dulled the high's- so I went back to spike's with the Magico's.  

I also really like Isoacoustics for speakers.  I started with GAIA for my floor standers and they were great.  Then I had stand mount speakers in another room.  I use the Aperta between the speaker and the stand.  Not only did I get the same sound improvement but also I could add some tilt.  I think they helped here even more as my stands aren't that great.

I did try the pucks for my turntable and I have to say that was a disappointment.  I guess the built in isolation was enough.  I didn't notice any difference but still have it installed as I couldn't return them and don't know where else to use them.

@emergingsoul   My Von Schweikert VR9 SE Mk2 upgraded which weigh 350lb each come with the company's engineered casters.  Easy to move and place while solid non-spiked contact.  They are on a thick carpeted floor over 12" thick 3000 psi steel reinforced floor.
