KEF Reference 5-Isoacoustics GAIA?

I’ve posted before about my KEF Reference 5 speakers.  I’ve been experimenting with placement and found that moving them farther apart made a big improvement.  I also am trying the suggestions—I believe by Audiotroy— to toe the speakers inward some more to tame the treble. I love how the KEFs reproduce piano and cello music but violins sound too harsh and screechy for my taste.  I think the toe in helps.  Also, the violin sound may just be a result of the digital (CD) source.  I will see how violins sound on vinyl.  

One question.  I’ve been considering the Isoacoustics Gaia or pucks.  My speakers are on a hardwood floor, currently resting on the included spikes.   I’ve been in contact with Isoacoustics and they can provide a threaded rod to fit the outrigger of the KEFs if I go withnthe Gaia.  Has anyone tried these Isoacoustics products with KEF Reference 5s?  If so, I’d appreciate your thoughts.   Audiotroy, I woud be very interested in your experience.  I know that these products probably won’t impact the treble but may tighten up the bass.
