AAA 100% Analogue - Pure Analogue Components Only from the Master Tapes.

Master Quality Reel To Reel Recording On RTM SM468 Tape. Given that all tapes age over time and most analogue masters are now between 30-80+ years old, Horch House’s skilled team has developed a bespoke ‘soft refurbishing’ methodology which, as an integral part of the copying process, restores a recording’s sound quality back to its original level. Sound engineer Christoph Stickel has a remarkable knowledge of the complex elements underpinning the audio quality of an analogue master tape, enabling him to assess, understand and restore a tape’s original quality and achieve the correct tonal balance according to whether it was recorded 30, 40 or 50 years ago.
