Great system!
I have a pair of Sashas as well, and have just started using Cerabase under my F-E HD09 rack. Used the Cerabase Slimline under my Wadia CDP, and Ceraballs under my ARC Ref 5 preamp.
I'm finding the sound to have suddenly lost some 'life' or maybe rhythm?! for lack of a better word. Also the warmth in the system(I run Lamm 1.2s seem to have gone)
However some instruments like double bass seem to be more apparent. Was this your experience as well? Or should I be attributing this to the refitting of cables after I installed the Cerabases?
Also, my dealer is saying I should consider Cerabases for the Sasha..I can't use spikes because of the softer type of hardwood floor. What do you think?
