The BURSON Supreme Sound V7 Vivid Pro Dual Version Opamps are high-quality amplifier parts designed specifically for Burson Audio products. These opamps are known for their exceptional sound quality and performance, making them a popular choice for audiophiles looking to enhance their audio experience. With this pair of opamps, users can expect superior sound clarity and detail, perfect for those seeking a premium audio upgrade for their home entertainment system.

These were used for about a year in a home audio system that I am piecing out because it is hardly ever used. These are about a year old.
