AM-777
OptiGain®
AMR’s OptiGain comprises of two-stages: the first is a Single Ended Triode (SET) valve-stage without any negative feedback to preserve the magical essence of the music signal. The second section is a pure power buffer stage using bi-polar technology to amplify the current to drive even the most demanding of speakers.
OptiLevel®
AMR’s OptiLevel® uses the highest-quality components, ensures the transparency and energy of the music signal passes through unhindered via a combination of our Single Ended Triode (SET) valve-stage with a software-driven volume control.
OptiBus® USB Input
The AM-777 can be connected to any PC via its OptiBus® USB digital input; all music content (including WAV, AAC, WMA, MP3 etc.) stored on a PC can then be played back directly with the signal integrity preserved in its full glory.

CD-777
Philps DEM DAC
At the heart of the CD-777 is a Philps DEM Digital-to-Analogue Converter. This unique chipset is not used in any other CD source and it produces a sound that is so natural and organic. It is the only CD source at this price range with a performance that is truly en par with vinyl systems.
OptiSample®
OptiSample offers full control of all sampling modes: Direct Mastering (AMR custom Non Over-sampling), Oversampling (2X, 4X) and Upsampling (96kHz, 192kHz) on the fly, via selection on the remote control. User has the choice of truly organic vinyl sound all the way to the contemporary high resolution sound.
OptiValve®
The analogue section of the CD-777, the AMR’s OptiValve® stage uses no operational amplifiers or solid-state devices, boasts zero negative feedback and pure Single Ended Triode (SET) valves for the most tonally accurate reproduction of music.
