Purchased earlier this year and it still holds up as a fantastic sounding kit.\n\nThe integrated DAC sounds very detailed and refined on its own - DSD files especially sound very buttery and smooth. USB connects easily to laptop or other devices such as a DAP. If using a PC/Laptop I would recommend using a streaming app like Qobuz which will connect directly to the HDV ASIO driver, allowing maximum listening fidelity. \n\nIt truly shines as an amplifier, especially when using the balanced XLR inputs, so having a balanced connection to your headphones is crucial to get the most out of this kit. I currently have the Schiit Bifrost 2 DAC connected via XLR and the sound is truly end-game. The headphones I am currently alternating between are the Sony MDR-Z1R (Rich base, great for rock/pop/hip hop) and the Hifiman HE-1000se (wide open soundstage, highly resolving) headphones which are less sensitive but both sound amazing. \n\nHighly recommend this kit for the price as you are getting a solid DAC with the capability to play DSD files as well as an elite amplifier section that layers and immerses you in the music.
