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.

I can't comment on the KEF speakers, but I just installed GAIA IIs under my Martin Logan Expression 13as yesterday, and after one night of listening I've determined they are staying there.  I'd agree that the two areas I noticed an improvement were better image focus and tightened bass.  I'm going to be getting a set for my subs now too.  very happy.  
The Kef Ref ranges cabinets are some of the best in their price point, there is a believe a white paper online for them explaining how they are made. Personally I’d be looking elsewhere in the system especially as you already have them sat on a hardwood floor. 

They Can’t do any harm,  I’m  not sure it will address the above mentioned issues. 

Just my opinion of course.
Personal experience with our own KEF Reference 5 display reveals them to be a touch on the mellow side, more than bright.  The electronic chain ahead of them is a very neutral one.  A speaker cable choice brought about a proper balance, along with, to a lesser degree, DAC filter choices.  Regarding IsoAcoustics our experience is a focusing of the sound, more than tonal alterations.
I got them for my Kef Blade 2s from Crutchfield on 60 day return ability.  They are staying.  I can't say they blew my mind like I was hoping but they make a nice improvement and I also like how they grip the speaker to my hardwood floor and make the speaker much less tippy.  Not such an easy thing to A-B with the factory spikes but overall I got a sense of improvement across the board.  Get a set from somewhere that allows returns and see for yourself.
