Grimm Audio MU1 - Feedback?

Link to the aforementioned product?
 
 
Hi All,

I‘m curious if anyone has had a chance to use the Grimm Audio MU1? Thanks.
Yes, I've owned one for 2 years and it's freaking amazing!!! More improvement in sound quality than any DAC I've tried. It has a very good clock which acts as Master (DAC = SLAVE) when they connect via an AES/EBU 110 ohms digital cable. Also, it is primarily a ROON device and can act as a ROON CORE. It is a very capable upsampling device. I leave the ROON settings alone (LOSSLESS default) and choose 4f upsample in the MU1 menu and Pristine Silky music flows out of my drivers and fills my listening room. My DAC is the DirectStream mk II DSD DAC by PS AUDIO and the combo of that and the MU1 is pure magic and synergy. HIGHLY RECOMMEND BOTH IN COMBINATION
 
I tried one here, didn’t make the slightest difference as you would expect.

It could run as a Roon ‘core’ but £10k for a puter seemed a bit steep.

Most, if not all will be unable to tell the Grimm from the Wiim. Proper test conditions given.
