isotek - RIAA Blue Horizon filter Audio component

Isotek RIAA Filter plus Full System Enhancer CD
New product, never used in its original packaging.

Description: Historically, to optimize a phono stage, new owners would have to replay LP records for at least 72+ hours. This would require playing LP records on the turntable, causing record wear, cartridge wear, and the need to spin the record, about every 15 minutes.
With the small but effective Blue Horizon RIAA filter you can now connect your CD player directly to the phono stage and put CDs on repeat. The most effective way, however, is to use this product in combination with the Isotek Full System Enhancer CD, which also features a dedicated burn-in track Phono Stage.
Each channel can be conditioned independently, offering excellent control and easy performance enhancement. Easy selection between moving coil and moving magnet cartridge designs.
Just connect the Blue Horizon RIAA filter to the phono stage input sockets and connect the CD player using standard RCA connectors and interconnect cable. Simple and effective. Each RIAA filter comes in a color-marked package for easy identification.
