Audio Electronics Listening Tests
Carefully-controlled listening experiments are important for best component selection and best decision-making. Stroud Audio Inc. has performed blind A-B tests both in-house and at the customer's location.
It's easy to convince yourself that one device or circuit is much better than another. Thrilling clarity or precise definition. I've heard it myself, only to find that the differences I've heard often vanish with the rigor of a properly done listening experiment.
Enthusiastic vendors can produce convincing demonstrations whose benefits are gained from slight tonal boosts or subtle volume differences.
If an electronic component or processing system creates a strongly noticed improvement, then if that improvement is real, it will not disappear during true objective testing.
