Streamer Comparison and Suggestions

@mitch2 if you are looking at Lumin, I have had the Lumin D2, Lumin P1 and I now have a Lumin U2 Mini with an upgraded power supply, I went with an S-Booster.  It doesn’t have to void the warranty, if anything requires warranty service you would have to put the original power supply back in the Unit.  On the Lumin products, upgrading the power supply is a really common upgrade, they make great products, support is outstanding, they are continually sending out updates to their units and software.  Bang for the buck, you won’t go wrong with the U2 mini with an upgraded power supply, it will get you close to something 3x the price.  I also had an Aurilac G2 streamer, not the latest version, the one prior, great streamer as well, I found Lumin to be a smidge better but you wouldn’t go wrong with either, the U2 Mini would save you some $$ but you wouldn’t give up any performance relative to the older version of the G2, can’t speak to the latest. 
 

If you want the best of the best as another poster mentioned Aurender products are about as good as it gets when it comes to streamers.  

+1 Innuos. I have a ZENITH MKIII and it’s been flawless. The Sense app seems to be the best available with a great sound, very intuitive and robust!

The Metrum Ambre is hard to beat for SQ.

The only way you’ll know for sure is direct comparison with return privileges.

I also returned SOtM and Sonore Rendu because their support could not get them to play anything BUT Room and limited IP radio.

Currently happy with Magna Mano Ultra (i2s), Pro-Ject S2 Ultra (USB) and miniDSP SHD Studio (AES-EBU), all with Qobuz and external SSDs.

Very good streamer is Melco.

I would echo comments regarding Innuos and the Sense application. I used a Zenith Mk III as a Roon core and streamer and it is an excellent sounding streamer. (I recently upgraded to an Innuos Statement but the Zenith is right up there.) It will run Roon and run DSP software. But for the best sound it is better if you utilize a separate Roon core and use the Innuos as an end point/streamer only. The processing power used to manage Roon and DSP tend to detract from the overall sonics. I compared the Zenith to Lumin and Aurrender products in similiar price ranges and found the Innuos to be sonically superior.  

Also agree with general comments about the Innuos Sense app. It works flawlessly. I spent a lot of time comparing the sonics of the Sense to Roon before switching and dropping Roon. It is easy to toggle and A/B between Roon and Sense to compare. It was clear that the Sense application sounded much better than Roon and it was not subtle. More open, more transparent, better dynamics. Finding a used Zenith MK III should not be difficult. Good Luck
