Briacasti M1s2 vs Lumin X2 vs Grimm MU2 ?

 

Greetings! After almost a decade away from the hobby, I woke  to realize that the digital landscape had changed dramatically.   The Levinson 390S just wasn’t going to cut it anymore…
 
I picked up a Bricasti M1se2 DAC with the built in network streamer, and it’s been eye opening to say the least. I really was trying and wish to still avoid having more than one more box solution (not a separate server/renderer or having a roon separate box. I’d rather not Roon at all! Luddite perhaps.)
 
TO that end I have been able to use JPlay (which sees the Bric on my network) to feed Qobuz to the Bric - and the sound is amazing so far. sometimes the interface running JPlay on the ipad is janky, and like all of us, i wonder about upgrades....
 
Also relevant, I don’t have audio files to play, and probably would not start downloading actual music files, more into just streaming.

SO. I really like a single box solutions and am looking hard at the Lumin X2 and the Grimm Audio MU2. 

I understand both these units have the ability to act as a preamp, but I’d rather avoid that topic for now, instead focusing on Streamer-DAC performance. How they SOUND
 
I realize the Lumin has its own software and is pan-ready for all the usual services (Qobuz/Tidal connect, Roon, even Amazon Music now), and that the Grimm has an integrated Roon core inside, so would be super easy to run Roon but also offers UPnP. I’ve read (and perhaps it’s not valid) that Roon based experience is awfully intuitive but sacrifices some quality?..The Grimm can also come with various TB of storage too 
 
Those are nice important features, for sure, and the experience of playing music, the UI, would be better than my current arrangement, but they don’t say anything about the SOUND
 
Anyone listen to either/or? The Bricasti is pretty, pretty, pretty good, so I’m trying not to spend more for some sideways action.
 
THANKS!

Bricasti preamp section is killer. If you haven’t tried it and that’s the reason why you’re looking to replace it, listen to it as a preamp.

I am mostly looking at the Grimm as it can replace a preamp to

Try and get a listen to the Bricasti M12. Has a killer analog vol pot so you can use it as a preamp

The problem with the M1 as a preamp is the relatively low output RCA voltage (1.2V) going into my relatively lower gain, lower powered amps (First watt Sit-5 monos), probably not enough drive into my not super high efficiency speakers.

Bricasti 1.2v,  6 dbm

Lumin X2 - 3V

Grimm +12 dbm

I had the Bric running it max output a pretty high gain preamp (Cary SLp-05) and in that system it was loud enough, but it was close.

I used M3 into pass labs xa30.8 via XLRs. Probably upgrading your amplification would make more sense. That’s my opinion.

“Well, that’s just like your opinion, man”  - The dude. wink

 

Kidding aside, the First Watt SIT-5’s are glorious. No way I part with them.
