Mine happened twice first time- unplug and restart did the trick this time- nothing helped i then plug in an external USB hard disk with songs and worked well dont know how to gain access to the SSD again the HEAP folder is not there anymore hmmmmm don’t know if you still have this problem or contacted Grimm yet, but came across an earlier post on this thread with exact same problem, with a solution provided by Grimm (you may have to look a few posts up & down): https://audiophilestyle.com/forums/topic/58754-grimm-audio-mu1-and-mu2-music-players/?do=findComment&comment=1260019 Grimm Mu-1 > Mola Mola Makua/DAC > Luxman m900u > Vivid Audio Kaya 90 Link to comment

Please let us know what you hear as you lower the fixed setting. I'm currently experimenting with a fixed setting of -7dB.

FredM Posted Monday at 11:19 PM Author Share Posted Monday at 11:19 PM Darko’s podcast with Eelco Grimm about the MU2 is available: https://darko.audio/2024/09/podcast-whats-going-on-inside-an-e18000-streaming-dac/ An interesting interview for sure, with nice insights on the level of detail and the collective experience that has been put in the design. The importance to have control over the various elements in the chain/signal path is made apparent. Grimm’s passion for quality playback is obvious, where every detail matters, with a ‘quite nice’ result 👍 Link to comment

I'm currently experimenting with a fixed setting of -7dB. Very interesting... I notice no obvious quality difference between 0db and any setting under 0db, which is line with Eelco explanation. I currently am at -15 to -20 and this is the perfect setting range for my pre (ARC REF6SE). aangen and PYP 2 Link to comment
photobillyli Posted 2 hours ago Share Posted 2 hours ago So it seems to me that there is no way to actually by pass the pre amp in the mu2, is my understanding correct? Link to comment
