@gerihifi I'm curious about how you arrived at - 7bB for the MU2. I assume you just iterated through various settings until your ears said this was the best setting.
Grimm Audio MU2 "Major Dac"
- Thread starter PaulB
- Start date
Hi, it's a general thumb-rule (my opinion) and not put it on max - always around 85% of max volume if preamp is attached. Also see Grimm FAQ:
MU2 FAQ - Grimm Audio
#1 Cannot log into Roon after database reset. After you performed a database reset you cannot login to Roon. Instead you are forwarded to the Roon login page. After returning to the Roon remote there is no response. To resolve this issue, please update your MU2 to firmware version V0.9.6 or...

- This rule doesn't apply in setting done mentioned earlier, as you set the MU2 to "Fixed Volume"
- As advised with "fix volume" in roon device setup, this doesn't apply as well:
BTW: Eelco Grimm mentioned to me that MU2 nativley supports DSD up to 256 (I completly overlooked that) and they also do their magic 1.5bit instead of 1bit data conversation. I tested some DSD256 albums and I'm pretty impressed - highly recommended to test!

For those who don't follow the MU1/MU2 thread on AS, Eelco Grimm responded to a query about the software update to add UPnP/DLNA functionality:
"The UPnP/DLNA function of the next big MU1/MU2 update will be JPlay and Audirvana certfied. It takes longer than expected due to external reasons I cannot comment on here, but also because this is a major firmware update that has impact on many aspects of the playback system. And also because the same software team has been working on the quite spectacular LS1 update that is currently in beta. Please keep a little more patience, we build all software completely ourselves for stability reasons and stuff like this takes time."
While I'm happy with Roon, it will be fun to experiment with the others and make a comparison.

I have all the things that would let me test UPnP/DLNA, I doubt I will race to try them. The MU2 with a Muon Pro System is just fine with Roon. Those other programs just don't match up to the ease of Roon. Bah. Audirvana is like a puzzle that constantly changes. Have a large DSD collection? That stops it dead cold. Bah. (At least it did for me)
completely agree that MU2 with Muon Pro using Roon sounds like music. Period.
A friend who uses Audirvana has experimented with many, many settings. To him, that process is enjoyable. It wouldn't be for me. I think JPLAY makes sense when used with their server because that is the reason one would by their server.
But, these additional capabilities will expand the market for the Grimm Audio products and that is a good thing. The MU1, and especially the MU2, could change the perspective about the fact that enjoyable music playback need not impose complexity on the end user.
