How to value recording, live audio and DJ gear

In recording and live audio, value can change quickly as connections, drivers and digital standards evolve.

For interfaces and controllers, check compatibility with current systems, transferable licences where relevant, ports, encoders and power supplies. For mixers and power amplifiers, test channels, outputs, fans and abnormal signals. For monitors and microphones, consider matched pairs, capsules, suspensions and physical condition.

With digital products, a perfectly working older unit may have limited value if software support has ended. High-quality analogue equipment may be less affected by age when maintenance and demand remain strong.

Real-world operation and current compatibility belong in the valuation alongside the model name.
