Many people hesitate to purchase secondhand equipment. Especially audio products tend to have a connotation of degrading over time. Therefore, people who are looking to purchase high-end audio systems rarely ever consider purchasing a secondhand product. However, let me explain that this might not always be the case. You can actually save a bundle when purchasing a secondhand unit versus buying new equipment.
First of all, a secondhand unit might be a product which has been used by customer or it might be a product which has been refurbished by the manufacturer. Products which have undergone refurbishing usually carry the original manufacturer warranty. Thus audio performance is also guaranteed by the vendor. So unless you are picky about cosmetics, you can purchase a refurbished unit without second thought.
Generally, refurbished products are 30 to 50% cheaper than new units. Given that you have the full warranty, a refurbished product is usually a good deal. Obviously, the packaging might be ripped or there may be some slight scratches on the surface. However, only performance is usually not affected.
Use products, on the other hand, have never undergone testing by the manufacturer after they have consoled. That means that there might be some elements such as volume controls or connectors that have worn out. Generally I recommend to test the product before purchase. If you order via mail then testing will not be possible. Therefore, negotiate with the vendor if they could unit if you’re not satisfied. You should have a certain time. Such as 10 days within which you can return the product.
Most modern audio devices use solid-state technology. This technology usually can last a long time. The only components which might be degrading over time are control elements such as the volume control. However, if you don’t often change the volume or if you work via remote control then this is less an issue. Also, if the remote control is worn out, many companies offer replacements. The remote control is usually a fraction of the cost of the full product.
