The finish Klipsch uses on the Heritage series is just oil. You can bring refinish them any time with Watco danish oil.
You can give them a very light sanding with 400 grit stearated silicon-carbide paper on a wood block being super careful at the edges and corners or you will go through the veneer. A good restorer could sand them a dozen times without going through the veneer. This will remove light scratches. Deep scratches you have to fill first. Then you wipe on the Watco with a clean rag, let it sit for 20 minutes then wipe it off with another clean rag briskly. If you want a little more gloss and protection you can repeat the Watco (no sanding!) at two week intervals until you are happy with the results. Watco is very slow drying taking up to 30 days to cure entirely. You can handle them in 24 hours.
Oily rags have been known to combust spontaneously. I soak them in water and throw them into a galvanized bucket outside for a week. Then they are perfectly safe.
