PTA: MU1 leads to “the very summit of the peak”

June 29, 2021

The highly regarded US online magazine Part Time Audiophile did a review of the MU1 and granted it their ‘Reviewers Choice’ award! Grover Neville was truly impressed by the MU1. In his article he summarizes a few of the thoughts that Eelco Grimm shared with him during an interview, talking about the unique up- and downsampling filters of the MU1. And then he describes his listening experience:

“Through the AES input it was (…) as if there was more detail, more transparency and a more coherent and dynamically liquid presentation. Imaging did not change in sharpness but did become denser and more tactile. Backgrounds seemed darker and images more separated and defined, without having their fundamental character changed.” 

“The moniker sticks in my head for those choice pieces of gear which don’t seem to alter the source in any other way than to make it better. Clearer, more resolving, transparent, whatever audiophile bingo term you prefer, the Grimm Audio MU1 does it”

“What it does offer fires straight to the heart of what I value most in hi-fi — the elusive and technically mysterious sense of engagement we get from the best classic gear.”

“If you’re in the pursuit of the best, I can see this server taking an epic system to the very summit of the peak. “
