Tolerance for component blemishes AND the amount of discount vs new to tolerate these imperfections is highly subjective, so sharing our individual preferences is not very helpful.
Generally, I except most used components to be at 30-50% discount vs new. If the OP loves the Totem Element Metal speakers in excellent “flawless performance” working condition, then the 5k price (75% discount vs new) seems like a subjective sonic bargain.
