The Grimm Audio MU1 to me, is a product that demands an experienced audiophile, and an experienced ear. It also demands a large pocketbook and a fanatical devotion to perfection at any cost. If you meet those criteria, and you’ve got an idea of why the technical sundae toppings of the MU1 make a difference, this unit might actually delight. It brings a level of digital refinement and ease to very good DACs that isn’t something you can really replicate with any other device that I know of on the market.
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. For the true digital perfectionist, this could very well be the perfect piece of summit-fi you didn’t know you needed. For the rest of us, there’s many great flavors of beer.
