The ultimate test on the performance of any musical equipment remain the listening experience in our home. From a technical standpoint however the result also need to be quantified accurately to confirm that the requested specification has been met. The equipment used to manufacture our idler wheels are also used to create parts in the aerospace industry requiring very tight tolerances capable of producing high precision components right down to the micron level - the very best in the business. This level of precision can't be analyzed by human eye or standard measuring equipment so we rely on advanced measuring techniques to comply and deliver the certificate of conformity required at the end of a production run.
