SA-KI Ruby With Signature Edition Upgrade
Marantz has been designing and making amplifiers for more than 65 years, and for 40 of those the products have reflected expertise of Ken Ishiwata. Now, to mark his four decades with the company, the SA-KI Ruby SACD player has been developed and tuned by a highly experienced engineering team led by KI himself. Features the same disc mechanisms as the SA10 that play SACDs, CDs and compilations on CD-ROM or DVD-ROM. The SA-KI Ruby includes an asynchronous USB input that handles formats up to PCM/DXD 384kHz/32bit and DSD11.2MHz and treats all digital music with a unique Marantz Musical Mastering technology. By up-converting all file formats to DSD, using advanced filtering and processing and direct 1-bit conversion to feed the analogue outputs, the SA-KI Ruby delivers sound with remarkable clarity, effortless dynamics and exceptional presence—plus, features a laser-engraved Ken Ishiwata signature to commemorate his legacy.
The Upgrade Company LLC continues to supply all of Marantz very latest models purchased directly from factory authorized dealers then expertly "Signature Edition Upgraded" inside to yield tremendously higher performance over the For Profit Built Marantz factory mass-produced RFI & EMI saturated signal distorted stock models.
