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! 😜
