I have replaced the front stock spikes and the rear rubber bumpers with brass spikes, as a first-step isolation effort.
My goal is to maintain the factory height from the floor and the factory angle - front to rear. [Note: the Nenuphar speakers are bottom ported]
I went with Eden Sound's Solid Brass Spike (extra large) for the front with it's matching Point Receiver (extra large) and the Solid Brass Hemi-Spike (extra large) for the rear.
Immediate performance / sound quality differences and upsides. I will report more later.
