Limited-time price reduction (3 days) The GUSTARD A22 is a DAC that supports 2.82MHz DSD sampling. Remote control included; antenna and power cable are third-party products, not original. At the time, it lavishly used the flagship model AK4499EQ (production discontinued due to a factory fire) from Asahi Kasei, independently for left and right channels. Power transformers are also independent for digital and analog. Operation shows no particular problems in use. The appearance is, in my subjective opinion, beautiful. The AK4499EQ has four channels built-in, while the successor AK4499EX has two channels. This product uses two AK4499EQs independently for left and right channels, making it a valuable product nowadays. - Brand: GUSTARD - Model Name: A22 - Output Terminals: RCA output, balanced output - DSD Sampling Frequency: 2.82MHz - Input Terminals: USB input, Bluetooth input - Power: AC • USB uses the dedicated XMOS USB audio chip XU208 and supports PCM768 and DSD512.
