The Ra range of earphones have become a bit of a legend since their launch, just like it’s smaller brother the EAMT1. It’s my all time favourite earphone range and provides undisputed levels of detail. The patented 2nd generation AMT tweeter is up to 5 times faster than a normal dynamic earphone and you can easily hear that when you begin listening to it. The timbre of this earphone is exceptional and very well suited to anyone who plays an instrument and knows what it should sound like. The Ra range excels when used with a source of similar quality that can provide it with enough power to make them sing. It’s enormous 16mm dynamic driver that works in combination with the 2nd generation AMT tweeter offers bass like a large over ear headphone. The aluminium and ceramic enclosure offers great durability and details with more purposeful bass than the copper version, however it isn’t quite as true in its representation of the music due to this.
The C version means that the enclosure is made of precision ceramic which, due to its inert properties doesn’t add anything to the sound and therefor is as accurate as it can be. There are other versions of the Ra with either aluminium or wood enclosures.
