AMR

The core DAC is the classic "King of the Multibit" – Philips TDA1541A chipset. This chipset forms the heart of an extremely unique “Digital Engine”
that comprises of the latest Lattic’s CPLD and TI’s DSP devices.

Combined with the revolutionary “Gomez” analogue stage using pure New Old Stock valves throughout and a total of 5 dedicated
audio specified transformers, the CD-77 brings the performance of CD back in-line with the very best vinyl has to offer.

Operation modes:

• Direct Master I; no digital or analogue filter
• Direct Master II; no digital filter, anti-sin(x)/(x) analogue

Able to play compact disks and computer audio to the highest level, without compromise and future-proofed for many years to come, the CD-777 can only be an AMR.

The CD-777 Compact Disk Processor upholds the AMR tradition of developing the most musically engaging components; by taking classic and modern audio approaches that are simple in concept, but challenging in execution. The CD-777 produces emotionally stirring music reminiscent of timeless, analogue replay. With an exclusive NOS Multibit chipset, bespoke transport and premium quality valves, backed with cherry-picked components, the CD-777’s atypical approach surpasses digital source machines costing several times more.

Mainstream components usually see functionality compromised. With the CD-777, rather, functionality has been taken to the extreme. The CD-777 is the first type of what AMR’s refers to as a “music hub”. Using the absolute highest quality design and execution, the CD-777 is first, a high-end CD processor. Second, able to receive a digital signal in from a PC or transport either through USB or S/P-DIF without the usual increase in jitter, it can be used as an accomplished DAC. Third, able to send out a digital signal through S/P-DIF to an external DAC or computer, it can function as an exceptionally well-designed transport source.
