Professional Speaker Cabinet Refinishing

I've seen several high-end speakers that sold used for a substantial discount because of what in my opinion look to be minor cosmetic irregularities (scratches, missing grill posts, torn grill cloth, missing binding post cap, etc.). For example, there was a pair of Dynaudio Contour bookshelf speakers that were on sale for $400. Are there any companies that refinish wood cabinets and repair grills? Is this recommended (ie. do they do a good job)? And what does this service typically cost?

I would go see your local cabinet maker, some are very talented with real wood veneers. possibly you could get both re-veneered.
