Please, please do not take your vintage audio equipment here! Before I really knew anything about the equipment I had, I took my Marantz 2330 to them for repair. Not only did they not fix anything, but they actually made my receiver worse by bypassing the protection circuit. I now have a frozen woofer on one of my formerly pristine AR3a’s. What a shame. They don’t know what they are doing, don’t stand behind their work, and are extremely expensive for the«work» they do. I have even heard of them redoing speakers and convincing people to trade out their original drivers for new ones. Not because it’s in the best interest of the client, but because they want the original part to resell. They don’t have the nickname«Audio Vultures» for nothing. Stay away!
