  #2. Short-pin-type RCA caps: RCA caps to shortcircuit + & - of input RCA terminals. Those could break the device if used for output terminals; Luxman, etc.

  #3. Metal cover-type RCA caps: May reflect not only the outside electromagnetic waves, but olso inside coming ones to confine them within devices; audioquest, etc.

  #4. Electormagnetic wave absorption-type RCA cap: Those that cover RCA terminals to absorb electromagnetic waves; Oyaide, cheeTarh, etc.

 

 

The Material Absorbs 99.5% of High Frequency Electromagnetic Waves!

 

チcheeTarh RCA cap is categorized in the last, and it consisits of carbon fibers, and does not contain metal at all. This will never reflect or confine the inner coming electromagnetic waves inside the devices. The same can be said for cheeTarh Outlet Covers. The electromagnetic wave absorption material cheeTarh Consulting uses is thin, but absob more than 99.5% of the penetrating electromagnetice waves. Similar material for a marketed product does contain sendust alloy, and the possibilities of inner reflection or radiation cannot be denied. In addition, as cheeTarh Consulting placed the material inside the caps or cover, it will mever come off, from the design viewpoint.

cheeTarh RCA cap is not short-pin-type, and can be used both for input and output terminals, but the use of output terminals is recommended both inanalogue and ditital cases. This was the result of careful listening tests. The technical  principle is not known, but the use for input terminals should be done with caution. The recommended RCA cap for input terminals is metal cover-type, and audioquest's RCA cap is the best one, as long as cheeTarh Consulting tested. This is just the results of cheeTarh Consulting's listening test, and you may find other thing better. EMC with not used RCA terminals for frequently used devices are not enough. The measures should be taken for all devices connected with RCA cables. It is also recommended that the  measures should be take all devices that are connected by power cables. This procut is solad by a set of 3 pieces.
