No special feet or tweaks for my modem.
As far as Bacch for Mac it’s addicting! The majority of my listening is with Roon playing thru the B4M. The Grimm MU1, The Ethos, and the Rega RP10 all have superior sound quality over Roon played on the B4M. What all those sources don’t have as of right now is XTC and ORC. The Mac Mini is not bad it’s quite good just not at the level as the previous mentioned gear.
The B4M is incredible. The Adio or Dio would be the machine to get if you expect high end audiophile quality. B4M responds well to all upgrades I’ve tried so far. Upgraded power cable, muon pro, and connection to GC 1.1 along with Ethos Dac.
If you enjoy classical music the best component in Hifi imo is the MBL 101 speakers. If you can’t afford MBL 101 then it’s definitely Bacch!!! The size and scale of the soundstage, instruments placed in space is perfect! The ORC and XTC is so good it makes the short comings with the MacMini and not having better power cables a non issue.
I thought with Bacch I’d miss DSD but I can’t say I’m missing DSD. I can still play DSD it’s converted to PCM by Roon. I look foward to hearing Bacch with CD’s and vinyl.
