Innerfidelity

Beside a subjective listening test, Tyll Hertsens always publish measurements for the headphone at test.

 

In 2018 AVTech Media Ltd (UK) acquires Home Tech Network.

Pretty soon after that , Tyll left Innerfidelity.

Innerfidelity was turned into a lifestyle oriented website full of the normal audiophile nonsense. In 2020 Innnerfidelity was terminated.

Tyll's legacy can be found here.
