This is where science enters audio. Made by Akiko Audio (an audio accessory manufacturer from Netherlands), the Tuning Stick, to put it in the lamest of layman terms, is a tuning device to suppress high frequency noise. Each “stick” is scientifically designed and encased in carbon fiber to “enhanced” (check out their lab test report on their website) the effect of the Tuning Sticks on the cables they are supposed to be attached to. The Tuning Stick you see here is the RCA type where you just plug it into any unused RCA input on your hifi component.
Cosmetically, the unit looks good with the usual minor scuff marks from use. It is one owner since new and will be securely packed for safe shipping.
