The WALKER AUDIO TALISMAN temporarily dissipates magnetic fields and static electricity allowing the phono cartridge or laser reader to transmit a purer, more accurate signal. Magnetic fields and static electricity can greatly affect audio and video playback equipment and source material. The Talisman temporarily dissipates magnetic fields and static electricity allowing the phono cartridge or laser reader to transmit a purer, more accurate signal. Use the Talisman to treat LPs, CDs, SACDs and DVDs. Distortion will be lowered and the sound will be more realistic. The soundstage will open up with improved depth and transparency. You will get more information without glare or harshness. Dynamics will improve and the harmonics will sound more natural. With video, you will get improved colors, focus and depth of image. The Talisman requires no batteries or power cords and never needs recharging.
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
I use a Walker Talisman to demagnetize my CDs and LPs every time I play them. The difference between a magnetized CD and a Talisman demagnetized CD is a warmer, smoother, less "digital" more analog-like sound. CDs build up a charge after repeated playings. Just one playing can charge it and demagnetizing it after one play revives the sound to where it started. The Talisman is just a big pair of magnets but works like a powered tape demagnetizer unit, but is non-powered, easy to hold and use and small item. I highly recommend it for quality audio systems (and works on DVD/Blu-Rays as well for video systems). However, on low end/low resolution audio and video systems, it may not work.
I also have an Acoustic Revive RD1 which does a so-so job and which I purchased prior to the Talisman. It's now in it's third iteration. Maybe the earlier ones were not sufficiently powerful. They are $400+, don't do records.and require A/C power.
