Sonic Barrier damping sheets vs cork

I like cork quite a bit particularly around circuit boards and transformers. Lead not so much.

In most applications I’ve tried lead it hurts the sound especially in the bass, makes it sound weird. And lead seems like SUCH an ideal material. Not too soft, not too hard.  Lol  Maybe you will have better luck than I.

Why not Sorbothane?  Mainly because Sorbothane is one of the worst materials ever foistede upon unsuspecting and gullible audiophiles. And it seems like the perfect material, right? Not too hard, not too soft. The only worse materials, if that's even possible, are lead and SONEX.
