This unit can play back the outstanding sound performance of
Super Audio CDs. This unit has the following major features.
• Low-noise low-distortion filter circuit and high-
speed HDAMSA2-type output amplifier with the
differential input type HDAM
• Playback of CD-R/CD-RW discs
• Playback of CD-R/CD-RW/CD-ROM discs
containing WMA and MP3 files
• Toroidal transformer
The SA-KI-PEARL features a toroidal transformer that
produces less vibration and magnetic leakage flux compared
to conventional power transformers. The materials and
manufacturing process of the ring-shaped core are strictly
controlled to reduce vibration, while the short-ring attached to the
perimeter of the transformer reduce magnetic leakage flux.
• Equipped with highly-selected audio parts
The unit comes with the same custom power block capacitor
used in the SA-7S1. The unit's power rectifier diode and
regulator are also top-of-the-line.
• Copper-plated chassis
• Headphone circuit component upgrade
The unit comes with a fully discrete headphone output circuit
and we've upgraded the circuits and components from the
highly acclaimed SA-15S1 for improved audio texture and
expressiveness.
• DAC Mode
By connecting devices with digital outputs, such as CD
transports or MD recorders, to the unit's DIGITAL AUDIO IN
terminal, the unit can be used as a D/A converter.
You can further enhance music tracks by playing them through
the unit's high-performance, high-sound-quality circuits.
• Double-layered chassis
• High-grade machined analog audio output
