Buying a Marantz Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it's repackaged with original accessories included. When you consider that a factory-renewed Marantz product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 1 year parts and labor warranty valid at any authorized Marantz repair center (you can look-up locations online here or call 800-654-6633)
Marantz, like all electronics manufactures, receives products returned for various reasons. In 2023 consumers returned 23 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened, it must be resold as refurbished or open box and cannot be resold as new again. The history and reason why a product was returned is not provided to us, thus we cannot provide any additional details regarding its past. All products are processed by Marantz certified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Marantz Factory Refurbished" product.
Most (not all) units are cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we cannot provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
