Audio enthusiasts often use the concept of "a suit" to assemble a system. This mainly means that equipment under the same brand will have great convergence in terms of sound matching and achieving the sound tone set by the brand. Of course, the equipment that makes up this type of combination can also be selected separately. However, in terms of maximizing the effect, the combination type should be the first choice.
The Marantz SA-KI Ruby SACD player is a product personally tuned by the famous audio master Mr. Ken Ishiwata. With the help of the brand’s more than 35 years of Marantz CD player expertise, this This product uses Marantz's exclusive high-end SACD/CD turntable purely designed for accurate audio reproduction - "SACDM-3", which is purely designed for audio and can play SACD/CD as well as CD-ROM and DVD-ROM collections asynchronously The USB input connects high-resolution audio up to PCM/DXD 384kHz/32-bit and DSD11.2MHz, and the USB input and digital input are isolated to block noise from the connected source.
In the decoding process, the Ruby player uses Marantz's groundbreaking "MMM-Stream" to upsample to DSD and perform filtering, and the custom-designed 1-bit direct "MMM-Conversion" converts DSD Into analog audio, the new analog output stage is equipped with Marantz HDAM-SA3 technology and low impedance output, the power supply is equipped with a toroidal transformer, and a dedicated headphone amplifier with a fully discrete HDAM-SA2 structure
The ruby ??integrated amplifier has There are Marantz high-resolution preamplifier stages and proprietary HDAM technology, which are derived from the switching amplifier design of the flagship PM-10 amplifier and have powerful outputs in power: 100W 100W (8 Ω), 200W 200W (4 Ω) , fully discrete, two-stage design ensures signal purity, the preamplifier and power amplifier sections use independent power supplies to reduce interference, the preamplifier is specially equipped with a toroidal transformer to ensure clarity and powerful sound, current feedback design and newly developed wide sound range Circuitry, HDAM SA3 circuitry ensures clear signal and optimal dynamics, MM/MC phono input features new discrete Marantz Music Advanced Phono EQ circuitry, thick nickel plated copper independent input terminals for CD and phono cartridges , plus Marantz original high-quality/high-purity copper-plated speaker terminals, linear volume control and new electronic volume system.
Ruby amplifiers feature high-quality construction with a double-layer chassis, 5mm thick aluminum top cover, solid aluminum front panel and copper-plated chassis, while carefully selected premium audio components: Ultra-low leakage current Schottky diodes, low-noise complementary transistors, high-grade resistors, newly developed custom electrolytic capacitors, audio-grade film capacitors and mica capacitors are all crucial factors in playback.
This combination focuses on bright and lively sound, and the tone is very transparent. It is suitable for matching with most bookshelf boxes or medium-sized floor-standing speakers.
