I have seen quarters used with great success. I realize they are 25 times as expensive of that of the pennies. But they do hold their value! In seriousness, I think the thicker coin helps, definitely worth the investment to try before you buy the Targets.
Floor Protection Discs
Good Morning Audiogon'ers!
Seeing if you could help me. I will be purchasing a pair of Target Audio HR70 monitor stands. Since they'll be going on a hardwood floor, I was also going to purchase Target Audio's 'Floor Protection Discs' to protect the floor. Is there a cheaper alternative -
