One meter pair of VH Audio Copper Spectrum ICs with Cu Eichmann Bullet Plugs.
I had both the Eichmann and WBT connectors on Spectrums and found the former more transparent and resolving.
Asking $200 OBO. Shipping from LI, NY. Rated an "8". Pic on A'gon. on which I have a 291 ranking, all positives.
I've gone to much more expensive ICs.
