Lumin X1 latest Review like we have been saying

For many years we have been touting the Lumin products as being one of the best sounding and best implimented paths to creating a fantastic sound in your system.

We sought to be a Lumin dealer after the A1 came out and pretty much got rave reviews as being the best sounding streamer out there, each successive product was better the new T2 is amazing at its price point and challenges $7k streamer/dacs/

The lastest review

sums up Lumins history and even offers a comparison of the X1 vs the Total Dac, and DCS and the Aqua Formula, we actually have tested the upgraded Formula V2 with the Statement and it does sound even bettter.
Summation the best sound the reviewer ever accheived was with the X1.

We sell some of the worlds best dacs, including T+A, Light Harmonic, Aqua Hif, Naim, Mytek, Bricasti, and with the X1 you have to spend $30-50k to better the X1, it is nice to see that other people are agreeing with exactly what we have been saying all along.

If you are looking for the best sound for the money, rock solid reliability, a fantastic feature set, Tidal, Qbouz, Spotify, Apple Airplay to play Youtube or Soundcloud, OTA upgrades, Roon endpoint, full Mqua, DSD and High data rate upsampling, upconversion and playability, solid build quality, built in volume control, the Lumin products are hard to beat.

It is possible to use JRiver with LuminX1.
It will have to be done with the network rather than USB inputs.
This  is what I have done.

The USB "input" is only for connecting a hard drive or flash drive with media stored on it.  You can't use it to connect to your computer.

You can’t connect a CD player directly to the X1.

You also cannot (to my knowledge) directly connect the USB output of a computer to the X1. The connection is through the network.

Why would you want to? Depending on the size of your library, a computer is a better way of storing and organising a large collection of music files, particularly if it is updated frequently. Using the network the X1 is isolated from noise from either the PC or the hard drive. You can use other software such as Roon or JRiver rather than the Lumin app. I use Roon primarily and stream from my PC.
