Akiko Audio RCA Tuning Caps

€ 9,50 each



Akiko Audio RCA Caps Rhodium 

To reduce the amount of RF/EMI noise that enters your equipment through the unprotected RCA input and output as much as possible, we advise using our special RCA caps.

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.

Our caps provide excellent protection, preventing high frequency radiation from entering the inputs of your equipment. 

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.

Attention to detail is important to us!

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