Asking price for Argon2 pair in near mint cond?

Hi everyone,

I have a pair of Amphion Argon2 bookshelf speakers (black) purchased new in late 2006, and in near mint condition, except for some trace scuffing on the bottom surfaces. They function as new and have always been pampered, never driven hard. Can someone tell me how much they would be worth at this point? I'd like to sell the pair, but I don't want to over or undercharge.

Thanks for your input,

Chris
