@kalali, pricey? Not considering the performance compared with other speakers in the same price group. The Cube Mini Nenuphar’s retail for £10,250 in the U.K.

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.

David,

I'm not surprised that  stepping up to a higher quality better  engineered brass spike would  be noticeable. Better vibration/resonance management is a worthwhile  pursuit. Particularly a speaker the high caliber of the Nenuphar will easily reveal the differences.
