The Ra range of earphones have become a bit of a legend since their launch, just like it’s smaller brother the EAMT1. The new 2020 version features revised internals with integral damping. Alongside this there has also been a major overhaul of the airflow through and around the drivers. Improving on the original Ra was not an easy task and the 2020 version has taken almost a year to come to ffruition. During this research and development phase it was also established that the cable was also a limiting factor in it’s performance. To that end a custom cable was introduced to the range in order to improve on Ra’s incredible performance. The new cable – called Newton Signature – consists of high purity copper and silver plated copper in a litz construction with a quick release 4 in 1 connector system. This will enable you to quickly swap between 4.4mm, 2.5mm, 3.5mm and 4 pole 3.5mm.
Ra is 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 Ra model enables you to have access to the impressive AMTII tweeter without the need for the flagship, Signature Ra C Cu copper version. The Ra features the same driver setup as the flagship Ra C Cu with it’s 16mm dynamic driver and 8mm AMTII, however it doesn’t have the copper body.
The Aluminium version of Ra has exceptional performance with a lift in the bass response due to the resonance of the all aluminium enclosure. 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.
