Magic CD

The by Jean-Marie Reynaud (JMR) is a specialized "burn-in" or "break-in" tool designed to accelerate the mechanical stabilization of high-end audio equipment. It is widely considered an essential technical instrument in the audiophile community, capable of reducing the standard break-in time for new speakers by up to ten times . The Story Behind the Creation

FLAC

If you are using a version of the disc, ensure it was ripped as a 1:1 lossless copy to maintain the integrity of the technical signals. Compressed formats like MP3 may strip away the specific frequencies required for the burn-in process. Magic CD - JMR Electroacoustique - jm-reynaud.com Magic Cd Jean Marie Reynaud Flac

Out-of-Phase Technique

: A common audiophile trick for using this disc is to place speakers face-to-face (about 30 cm apart) and wire one speaker in reverse phase . This causes acoustic cancellation, allowing the drivers to move vigorously while significantly reducing the actual noise in the room. Magic CD The by Jean-Marie Reynaud (JMR) is

Component-Specific Treatment

: The 11 tracks target different parts of the system: Tracks 1–5 : Designed for woofer suspensions. File Size: A true 16bit/44

Full-spectrum Pink Noise (20 Hz – 20 kHz) used to "finish" the break-in for all components and cables www.jm-reynaud.com Optimization Tip: The "Face-to-Face" Method

  1. File Size: A true 16bit/44.1kHz FLAC of a 60-minute CD should be roughly 300MB to 450MB. If it is 80MB, it is a transcode.
  2. Tracklist: The original Magic CD usually opens with "Audience de la classe" (a field recording of a clapping crowd). If your FLAC starts with a pop song, it is fake.
  3. Spectrogram: Use Spek (free software). Look for a sharp cut-off at 22kHz. If the cut-off is at 16kHz or 18kHz, it is a lossy file repackaged as FLAC.

Volume Control

: Always start with the amplifier volume at zero before starting playback.

6 – 7

Centered at 22Hz with varying bandwidths (10Hz to 1000Hz) to loosen the spider and surround. Bass/Midrange Cones

  1. Dynamic Contrast: The difference between the softest whisper and the loudest crash must be extreme. JMR speakers have no compression; they need material that doesn't compress the life out of the waveform.
  2. Natural Timbre: Reynaud voices his speakers to sound like live instruments. Therefore, a Magic CD must feature unamplified instruments (piano, violin, acoustic bass) recorded in a real space.
  3. Low Noise Floor: The disc must be mastered with minimal compression and no "loudness war" clipping.
