My review concerns use in HiFi with a Coax cable. It has impressively clear sound, not tiring at all in the highs. If connected with a linear power supply, the bass becomes deeper, the high frequencies become even clearer, and the soundstage opens up impressively. In combination with a good Digital cable, it approaches a 1000 euro DAC, leaving behind all the cheap Chinese DACs. It is also worth mentioning that it has a Dual mono design which offers excellent channel separation and stereo imaging. I have only tested the headphone amplifier with the Sennheiser Momentum 2.0 and it works flawlessly, I have no complaints. I liked it so much that I bought a second one from eBay for the PC. I recommend it 100%. Due to its neutral and clear sound, it fits almost all HIFI systems and computers.

Very clean and very musical. Connected to a PC via USB cable for playback through audirvana. The USB cable is not included in the package. Therefore, for use with a PC, you will have to consider the cost of the cable that you will have to purchase on your own! Overall, it seems to have very good construction and appears to be durable... The headphone amplifier it has is a joke.... It's worth buying it to use as a DAC. If you have headphones with high impedance, it will disappoint you.... Personally, I tried it with the Sennheiser HD 580 that I use, which have 300 ohms, and it was like my phone was driving them... Nevertheless, I will give it 5 stars because I bought it for the DAC and as a DAC, it exceeded my expectations for the money.
