Hmmm... I tried Symposium Ultra today with my Microseiki/FR 64s/Koetsu and the result was interesting. However, the only thing I had on hand that is tall enough to give clearance for the turntable is a set of aluminium speaker spikes.The bass cleaned up very nicely with more transient attack, better definition and more slam. Detail seems to be better as well. However, I lost a bit of the Koetsu lushness and warmth in the midrange. The midrange does becomes clearer, the smoothness is still there. I would say that the midrange is heading toward being aggressive but not quite there yet.
I guess I will have to experiment a bit more with the footers to maintain the improvement in the bass but does not lose the lush and warm midrange as well.
