Best Server To Run Roon Core

@lalitk so if I have a fairly optimized system running Roon core on a Nucleus+, and desire usb input and output, what should I consider as a core only upgrade?

@sns Thanks.  I misspoke here; I have USB hard drive and Ethernet into Nucleus+, and Ethernet out to my Switch and streamer.

@lalitk Thanks, I have heard good things about Wolf.  My Nucleus is working fine, but I have a history of issues and repair.  It is about the last thing I have not taken to the next level.  BTW, I am awaiting Muon Pro from NA when available, and will be trying it in both of my systems and most likely keeping it in front of my Aries G2.1 Streamer.  Fortunately, the regular Muon works great into my Makua w. DAC and streamer, but not into my Aries, which craves the 1G input.  Take care!

@lalitk, Hello!   I now have my Muon Pro Streaming System (which means includes the second cable, which is by the way distinct for the Pro version). 

Recall I have Gateway 1100 Verizon Modem > JCAT M12 gold cable > M12 Gold Switch w/ Jcat Optimo 3 power supply > M12 Cable > Nucleus +

                                                             >M12 Cable > JCAT Net Isolator (coupler) >

Supra Cat 8 20 M >(WITH OR WITHOUT MUON PRO FILTER SYSTEM) > Aries G2.1 Streamer w LPS > USB (K-S Realization)  > Mola Mola Tambaqui > Audionet Pre and amps.

So I tried with and without the Muon Pro directly in front of my streamer. I listened casually for a few days to run it in, then did some serious A/B switching the Muon Pro in and out.  My wife has good ears and for her it was blind as I was the wizard behind the components.

1)  I had no issues with turning the Aries on and off and changing the cables quickly, and the Aries connected immediately.  This is showing the Gigabit put through of the Muon Pro vs the bottleneck I had with the previous regular Muon.

2) The Muon Pro adds significant improvement to our ears vs the straight-in Supra cat 8.  The sound was bigger, richer, more enveloping and just plain more pleasurable.  There was no doubt to us, and it was immediate.

3) The Muon Pro is connected with another JCAT Net Isolator into the Network Acoustics Muon Pro cables, One is hardwired out of the Muon Filter; the other is the second Muon Pro Network cable going from the Net Isolator (coupler) into the Muon filter.  My point here is that the second Muon Pro cable AND the JCAT Net Isolator could be helping.  Certainly Rich at NA says the second Muon Pro cable is important.  An interesting test would be to simply use the Net Isolator and one Muon Pro cable (leaving the Filter out) and see if they help by themselves.  This is only academic to me, as I love the sound of the Muon Pro Filter.

4) I can soon test the original Muon Filter against the Muon Pro  in my Mola Mola Makua system.  The embedded streamer is less sensitive to the 1G requirement, and works flawlessly with the original Muon.

Hello,  tonight I was able to do a head to head comparison of the original Muon Filter System and the new Muon Pro filter System.  Using my Mola Mola Makua  (the Makua is an amazing pre-amp with optional onboard Tambaqui DAC and Streamer), Audionet Max amps, Revel Salon 2 speakers and REL subs, I was able to easily swap in and out the Muon and Muon Pro.  My Makua (unlike my Aries G 2.1) easily accepts ethernet through either the Muon (100Mb/s) or the new Pro version (1G/s).

I listened each way for over and hour, then, formulating a clear opinion, I switched in and out for specific tracks. I was able to hear the difference each time within seconds.  The Pro is more engaging, more immersive, richer, tonally more pleasing, more relaxing, yet still just as resolving and tingly. I used Liberty; Alison Krauss and Union Station, It Doesn't Matter; Mark Knopfler, The Scaffolder's Wife; Old Genesis, and Chris Botte, Summertime.  The soundstage on Summertime is sky high with the Pro!

@Lalitk, I would like to experiment with placement of the M12 switch.  I do suspect it would sound best in front of ONE of my streamers.  But I need the switch where it is - between my Modem, Server and both Streamers.  Moving it around requires unhooking lots of things (specific M12 Telegartner cables), inserting an inferior switch etc.  Perhaps I will get to this.  Or perhaps I will order a Grimm MU1! 😜

Hello @lalitk , 100% agree!  I would keep my Muon Pro and M12 in front of  MU1.

The Grimm would run Roon Core (Server)  and AES (Streamer) into my Tambaqui, and also serve to my second system's streamer via LAN.  Only downside is not being able to use AES from Grimm MU1 into BOTH of my DAC's!  If had only read amazing things about MU1's AES output into the Tambaqui.
