iFi use two Burr-Brown DAC chips and the new 16-core XMOS chip to process the data received via the USB and S/PDIF digital inputs. This means the iDSD Diablo can handle up to PCM 768, DSD 512, 2xDXD. Both PCM and DSD remain ‘bit-perfect’. It also provides full MQA decoding! And with MQA now available over S/PDIF, you can take advantage of any MQA CDs in your collection.
