I have a Lumin T2 with my M4's and it sounds amazing! I do not use Roon only Tidal and with the T2 I can use the Tidal app and bypass the Lumin app. I though the Lumin app was horrible when I first started using it but I got used to it, still prefer using the Tidal app though.
I have been enjoying the Lumin U1 Mini. The Lumin app is not a great UI, but I switch back in forth between Roon and the Lumin app. The SQ is amazing!
Can anyone report on Innuos products. Am looking at the 3K zen mk3. Am currently a microRendu 1.4 with LPS 1.2 user. Sonore has been good to me in terms of customer service— thank you Jesus!—but it goes offline randomly and messes with me too often. The Innuos is reputed to be dead simple and have a very good app. Anyone agree or not?
I had the opticalRendu and I kept experiencing the music dropouts, so I understand your frustration. I don’t know about the Innuous products, but the Lumin has been very reliable and sounds great. So far, I haven’t experienced a single dropout and no app crashes.
