I seems that in every product category (yes, high end fuses ARE a product category), there's a desire to create a product in a space not yet occupied. Elevating the price point 2x the existing "reference" is nothing new in high end audio. And, in each and every case, highly energetic discussions occur challenging their cost vs performance.
For the "right" system, this $595 fuse might be the best bang for the buck invested to date in the system. Or, not. Only a listening test will determine their true value to the listener.
