@efoo I heard the Hifi Rose streamer at a dealer and it sounded very nice, but it’s hard to compare without hearing it in my setup.
I owned the Sonore MicroRendu & OpticalRendu w/external power supply, SOtM sMS-200 Neo SE w/sPS-500 external power supply and the LUMIN U1 mini. I still have the LUMIN U1 mini in a second system, but I bought the LUMIN U2 for my main system. LUMIN is very reliable and you get quick responses from the LUMIN rep. Peter Lie when you have questions. The Sonore and SOtM streamers are hard to beat for the money, but they are better paired with Roon, so I preferred the LUMIN for the better sound quality, reliability, constant software updates, and the ability to play the streamer as a stand alone with Qobuz, Tidal and local music files. I’ve gone back in forth comparing the LUMIN played through Roon and without Roon and the LUMIN sounds better without Roon although I think Roon has the best user interface and music cataloging. The only con I have for the LUMIN is the user interface. It is not very good IMO compared to Innuos or Aurender. Just my opinion.
If you have the money to buy two units at the same time to have a streamer shootout, that would be the way to go, but having the option to return for a full refund for the unit that you didn’t want. If you find a dealer that will allow an in-home demo would be the best option.
That being said, I recommend LUMIN.
