The weihrauch is quieter than the bsa - ive got both, but only because my BSA R10 se came with a vc on it - and i have also opened them both up to have a look inside b4 , and i found the fabric packing around the (hair curler) inside the HW to be a bit more denser than in the bsa vc, but there is not a great deal in it sound wise tbh - However if i had to choose between them, the weihrauch wins always, as its also feels more well made than the bsa vc. Ive heard getting, or changing the both inner washer/baffles to suit the right caliber helps reduce sound? but that is just hear say. Good luck m
