Akiko Audio RCA Caps

Akiko Audio RCA Caps

The Akiko Audio RCA Caps are designed to reduce the amount of RF/EMI noise that enters your equipment through the unused and unprotected RCA inputs and outputs. The Akiko Audio RCA 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.

The Akiko Audio RCA Caps provide excellent protection, preventing high frequency radiation from entering the inputs of your equipment.

Akiko Audio RCA Caps

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

Treating your equipment with the Akiko Audio RCA Caps will result in a reproduction with a ‘black’ background, causing the details to become more audible. The noise floor will be reduced considerably: less noise means more music!

The Akiko Audio RCA Caps can be combined with the other Tuning products. Especially recommended together with the Triple AC Enhancer, Tuning Stick AC MkII and USB Tuning Sticks. Using multiple products improves the results even better.
