Those look quality Marco, As you know I use Ortofon's LW-800S, pure silver headshell lead wires and find them excellent.

Good silver lead wire brings that bit more clarity and information, instruments sound real ie: piano lines sound like a piano being played, bass has bass note and texture rather than boom/wool/fluff/muff , if you get my gist.

Hi-hat, cymbals shimmer, again with a more realistic/natural tone.

I'm sure this is in some part down to how the nature of pure silver transmits the signal IMO.

Those must be seriously top quality Marco at more or less double what the Ortofon's pure silver offering goes for.
