I picked up a set of nice Klipsch KG 4.5's. I have a few questions: 1. There is some paint missing on the top and on a few spots on the sides. What can I do? Wax pen? 2. I have a few receivers, I was looking for a recommendation of what to use ... best match? - Luxman R-117 - Qinpu - A-6000 MKII - Tube Integrated - Onkyo 8050 Network Receiver - Sony STR-GX6ES - Marantz 1060 (needs some service) I use a Mac Mini/Firestone Dac as my source. Thanks!
