For me, they can be trusted as a means to see the product's aesthetic, as a photo taken to add allure to the marketed item.
Additionally, there can be other supplied info, worthwhile noting, i.e, the interfaces, references to more expensive than usually seen components selected for the circuit and measurements for the function of the circuit's design.
For many a potential customer, this exposure to the product is enough, and a shortlist item is added.
Having a demo' for me really matters; end sound evaluation and the impression made are where the audio interest lies, and long-term relationships with audio equipment are created.
I have no recollection of rejecting an audio device for the aesthetic, possibly a deselection due to the interface, never for circuitry, topology or the Math for the design; without this in place their is no functioning of the device. Plenty, and I really mean plenty, are rejected as a result of the impression the end sound is able to create.
Few are kept and maintained as a result of the impression of the end sound produced when used within the owned system.
Ad's or Reviews don't do end sound for an assessment.
