個人比較常用的是Densen DeMagic與AYRE/CARDAS SYSTEM ENHANCEMENT DISC(大都用Track 7 Full Glide) [約每週同時使用這2張一次]

Densen DeMagic另有一個不為人知的功用是可用來調整喇叭擺位進而調整相位



"Irrational, But Efficacious", the System Enhancer Disc from Ayre Acoustics, Inc. is excellent in breaking in components and cables, integrating sub-woofers with other loud speakers and features both a short and full glide tone sweep. "Tune up" your system in under 20 minutes!

The main tool is a five minute glide tone, that when played through your system at a moderately low listening volume, will improve its sound. While we don't have conclusive proof of the mechanism involved, we suspect that it functions by demagnetizing residual fields that build up in your components over time. We recommend playing this track on a periodic basis, from perhaps once a week to once a month. We put this track at the end of the disc so that it can be easily played even if the system is unattended. The other tracks have more specialized functions.

The tracks on this disc were created digitally with 88.2 kHz, 32-bit resolution. Enhanced resolution transfer to the 44.1 kHz, 16-bit CD format was performed using 0.5 bits of dither with a triangular probability distribution function for maximum fidelity.

Selections:
Short Glide Tone: This 60-second track contains a 45-second glide tone that sweeps from 5Hz to 20kHz, preceded by 5 seconds of silence and followed by 10-seconds of silence. This track offers a quick system "tune-up" for those times when you just can't wait five minutes for the full glide tone.

White Noise: Uncorrelated stereo white noise with a peak level of -12 dB. White nosie is purely random in nature and is chiefly used with test instruments for specialized measurements. The track lasts for 180 seconds and features a 2-second fade in and fade out.

Pink Noise: Uncorrelated stereo pink noise with a peak level of -6 dB. Pink noise is low-pass filtered to achieve equal energy in each octave, and is also commonly used with test instruments for specialized measurments. The track lasts for 180 seconds and features a 2-second fade in and fade out.

Brown Noise: Uncorrelated stereo brown noise with a peak level of -3 dB. Brown noise is low-pass filtered to closely mimic the spectral distribution of music. This signal is excellent for use in breaking-in components and cables. The track lasts for 180 seconds and features a 2-second fade in and fade out.

Mono Brown Noise: Identical noise signals in both channels. This track can be very useful when integrating sub-woofers with other lous-speakers. The track lasts for 60 seconds and features a 2-second fade in and fade out.

Out-Of-Phase Brown Noise: Opposite-polarity brown noise signals in each channel. This track can be used to minimize the actual sound levels when breaking-in equipment, due to acoustic cancellation between the channels. The overall sound level will be minimized when two loudspeakers are placed as close together as possible.

Full Glide: This 300-second track contains a 285-second glide tone that sweeps from 5Hz to 20kHz, preceded by 5 seconds of silence and followed by 10 seconds of silence. Please be sure to play the entire track without interruption. Try it, you'll like it!

LP則使用CARDAS MK2 FREQUENCY SWEEP AND BURN-IN RECORD



The Cardas Frequency Sweep and Burn-in Record is a unique tuning tool for system set-up, diagnostics and maintenance. It was produced by George Cardas and mastered by Stan Ricker. The "Sweeper", in addition to the standard tones, includes relative and absolute polarity checks, vocal channel identification and frequency sweeps that ultrasonically clean the cartridge stylus and degauss the entire system. And, locked, pink noise grooves that repeat endlessly, blank plateaus, even a sync label to check platter speed. All on a 180 gram pressing with a smiling Stan cover.

Selections (Sweeper):
1000 cycles, -14db
Sweep 30Hz to 30KHz, -14db, 2 ch., in phase
Sweep 1KHz to 30KHz, -14db, 2 ch., out of phase spiral
