Akiko Audio Tuning RCA Rhodium Tuning Caps are a plug in upgrade for the spare RCA inputs or outputs in your audio or video equipment.

The Tuning Caps are made from copper, a material that is exceptionally well suited for the job. Moreover an extra layer of metal, gold or rhodium, is applied for sustainability reasons and as a nice finishing touch. Both metals have a subtle influence on the sound rendering: gold makes it sound warmer, rhodium a bit more neutral.

They work by reducing the amount of RFI and EMI noise that enters into the equipment through unprotected RCA sockets. This unique property is further strengthened by the Akiko Audio RCA Tuning Chip, applied to each cap.

The recently developed energetic Tuning Chips are able to harmonise energy currents in places that were previously inaccessible to our other tuning products. The Chip is able to do this by permanently applying harmonising energy there where the Chip has been placed.

On top of this the Akiko Audio RCA Tuning Caps are cryogenically treated, making the crystal structure of the copper more regular. Each cap comes with an energetically treated 10mm Akiko Audio Chip.

Providing your equipment with the Akiko Audio Tuning Caps will contribute to a sound rendering with a ‘black’ background, causing the details to become more audible. The noise floor is reduced considerably: less noise means more music!
