oddly enough I just picked up my Ayre C5XE from Ayre Acoustics in Boulder after a small repair. The gentleman there asked if I had ever tried the myrtle wood blocks and gave me three to try. Why not,Right? I still have my minds jury deliberating, but my first impression was more Bass. So I will keep experimenting and determine if there is an improvement. The whole isolation from vibration makes sense, it just comes down to which is best. I have freind that swears by Black Diamond. I have used AQ Sorbethane feet for years under my TT and DVD-recorder. So why not a natural substance like wood? Hmm, maybe Aloe Stalk.....
