The death of KMET in Los Angeles was a turning point in my young father's life. I was 6 years old when it signed off permanently, ending commercial viability of the progressive, freeform rock format on L.A.'s FM dial.

It's also one of my earliest memories: Windows down and heater up on a cloudy February morning, sitting backseat in an Arby's parking lot before kindergarten, the sound of heresy on the airwaves. Its replacement was Smooth Jazz. We—my father and my 6-year-old self—hated it.

For several months, my wife and I had been living in a cozy studio apartment in New York's Financial District while our apartment underwent substantial renovations. All the old furniture was sold or donated, and decades of accumulated stuff was subjected to triage (sell, donate, or store). All my audio equipment, parts, and tools suffered the same fate. Downtown, my listening was via pretty decent headphones (B&W Px8, Audeze LCD-XC) connected to a Mytek Brooklyn+ DAC and my PC. Meanwhile, we were very busy shopping to equip the "new" apartment.

An all-in-one streamer-DAC-preamp would not have held much appeal for me if my old system was up and running. This, however, was a different time, and I was offered the Grimm MU2 for review with ideal timing.
