In the constant evolution of its propriety mastering process, 2xHD has progressed to a new phase called 2xHD FUSION. Integrating the finest analog with state-of-the-art digital technology.
The mastering chain consists of a selection of high-end vacuum tube equipment. In the case of analog masters, the master tapes are played using a Nagra-T tape recorder, modified with high-end tube playback electronics, wired from the playback head directly to a Telefunken EF806 tube, using OCC silver cable. The Nagra T, with its four direct drive motors, two pinch rollers and a tape tension head, has one of the best transports ever made. A custom-built carbon fiber head block and a head damping electronic system permit 2xHD FUSION to obtain a better resolution and 3D imaging.
If the master is digital, a chain consisting of a selection of high-end vacuum tube equipment is used, which includes a modified vacuum tube NAGRA HD dac (DSD) making it possible to obtain a real analog sound from a digital master. The 2xHD FUSION mastering system is powered by a super capacitor power supply using a new technology that lowers the digital noise found in the lowest level of the spectrum, something that was not possible before.
In both cases, the resulting signal is then transformed into high resolution formats by recording it in DSD11.2kHz, using Merging Technologies’ Horus A to D converter, which is also powered by a super capacitor power supply. All analog and digital cables are the most state of the art available today. The process permits the fusion of the warmth of analog with the refinement of digital.
Finally, the vacuum tube NAGRA HD dac (DSD) is used as a reference digital playback converter in order to A and B with the original analog or digital master.
2xHD was created by producer/studio owner André Perry and audiophile sound engineer René Laflamme.
