    High system delay and noise when doing sweep in REW

    Any measurements for Lehmann Linear/Linear SE?

    Hi All, As I didn't find a thread for headphone amp measurement requests, I'll just post this here. The Lehmann Linear is used as a reference amp when showcasing headphones like the Sennheiser HD800/S, and several mastering/recording studios in Europe seem to use it as well. However, I can only...
