Hi, there are other devices at this price range that are only streamers, including the Sonore UltraRendu v3, the Mano Ultra mkiii (that comes with. Farad power supply), the Silent Angel Munich, Volumio Rivo and PS Audio Airlens. The PS Audio Airlens, Mano Ultra and Silent Angel have i2s ouput, whereas the UltraRendu and Volumio Rivo have usb output. I'm currently using an UltraRendu Volumio Rivo and the Matrix Element S. All 3 are solid performers and I've never had any issues with any of them. The Volumio app is top notch. The UltraRendu has no app and I use it as a Roon endpoint, but it's so easy to set up and reliable. I have to say that Matrix has been working hard to bring software upgrades for the app and also firmware updates to the Element S after it received Roon certification.
I am using the UltraRendu, LHY clock and Gustard U18 with the Gustard R26 and the sound I'm getting is really good. Very organic and relaxed, but also resolving with excellent imaging and soundstaging. I'm very happy with the combination right now.
I hope this helps.
