I have had quite a few DACs and interfaces over the years and all had their flaws and highlights. This is no exception. I made a list of pros and cons after using it for a few months and the cons are considerably longer than the pros. However, the pros are so strong, I could not justify replacing it.
Pros: This is a dream when it comes to conversion. The details and transparency on both AD and DA side of this interface are outstanding. The build quality is outstanding, maybe with the exception of the main volume knob which feels cheap in person. This is a tool and as such it was built with less features and "nice things" than some of my past interfaces.
To name a few cons: there is no delayed relaying when turning it on so if you have a Furman without sequential power on you will hear a loud noise when turning everything on. Same applies to all outputs and inputs which is very annoying. There is no gradual mute/unmute. For the life of me I cannot figure out how to ensure that my settings stay the same every day. I did try following the manual but I cannot get it to work consistently, most days I start by setting everything up again in the Lyra application. Also, I would not bet on this master volume to function for years, it feels cheap for a high-end product but again, you might use it with a monitor controller anyway. It has an ethernet connection on the back which does nothing, I would love to see a Prism monitor controller that could be used through that port and would extend the life of the potentiometers on the device.
Overall, highly suggested, I never heard a converter better than this, so do not have second thoughts if you think about purchasing this.
