will make my remarks plain, short, and sweet. The Yamamoto
PB-9 Ebony Cones and PB-10 Ebony Cups are fastballs
down the pipe. They can be used separately (the cones
under a CD player and the cups under speaker spikes,
for instance) or together, as I did. I had the same
positive results with every component I tried them under.
They did no harm that I could detect, but enhanced the
sound, with deeper and more focused bass, richer tonality,
and, as with most cones, an added measure of precision.
The Yamamoto bases are a relative bargain. Try them
out. I think you'll be impressed enough to buy a few
