Neo-Classic 250, leverer følelser og oversætter med rene forførende evner essensen af musik, afhængig af årtiers kredsløbsforfining med komponenter, der maksimerer dette klassiske push-pull-design. Vælg enten de soniske forførende egenskaber ved triode eller den mere kraftfulde tetrode-konfiguration. De store oksekødskondensatorer giver øjeblikkelig energi til dynamisk ydeevne af forbigående toppe og kraftig baspåvirkning.
