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 wear to the record, wear to the cartridge, and the need to rotate the record, about every 15 minutes.
With the small but effective RIAA Blue Horizon filter you can now connect directly your CD player 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 for Phono Stage.
Each channel can be conditioned independently, offering excellent control and an easy performance upgrade. Easy selection between moving-coil and moving-magnet cartridge designs.
Just connect the Blue Horizon RIAA filter to the phono stage input jacks and connect the CD player using standard RCA connectors and interconnect cable. Simple and effective. Each RIAA filter comes in color-branded packaging for easy viewing.
