★ Full discrete pure Class A amplifier installed! Headphone amplifier with built-in all-in-one DAC using patented technology "current mode amplifier technology".★

◆ CMA 600i is an all-in-one model equipped with DAC, headphone amplifier, preamplifier.

◆ The amplifier section of this unit is equipped with a pure Class A amplifier of full discrete configuration using patented "current mode amp technology". "Current           mode amp technology" is a proprietary current amplification technology. By performing the core part of the amplification circuit in the current region, we have realized     surprisingly low distortion and ultra wideband amplification. The DAC section supports the industry's first true DSD mode.

◆ True DSD mode is a technology to transfer DSD directly from the computer, not to DoP (DSD over PCM) during USB transfer. By doing this you will be able to enjoy        the true DSD sound (※ application is necessary separately). In addition, Asahi Kasei Technologies' AK4490 "is used for the DAC chip, USB input supports native          playback of PCD up to 384 kHz / 32 bit and DSD up to 11.2 MHz.
