Oyaide SLSC RCA plug with silver center pin


I would like to ask if anybody have had a chance to evaluate top of the line Oyaide SLSC RCA plugs with silver center pin.
These plugs are very well build and I am curious how they compare to WBT NextGen with silver pin or even better WBT plugs OEM for mundorf (with silver/gold center pin).

I am interested in retermination quality tonearm cable, so maximum transparency and neutrality is needed
