I have a Yamaha AX-570 Natural Sound Stereo Amplifier and a Yamaha EQ-550 equalizer for sale. I bought an entertainment center from a guy a few months back with TV, shelves, speakers...etc. He had these two (along with a bunch more that I do actually use) components as well as part of the package. He was big into karaoke, but I am not. I have never even used these. They are in excellent condition, you cant even tell they have been used. The guy I bought the system from made custom dust covers and mats for all of his equipment, so I have those too. I have some idea of how much they are worth, but I am really not too sure. Anyone interested, shoot me an email offer. I have pictures of both components as well that I can email if you want them. Here are two links for reviews of these products. AX-570 AMP Another AX-570 EQ-550 Thanks
