The N31 is expensive, at $15,400, but, as I said in my review’s conclusion, digital audio engineering doesn’t get any better and neither does digital sound quality. However, I also wrote that the N31’s absence of a volume control might be a problem for those who’ve sold their preamplifiers, as will be the lack of a network port for those who’ve banished their noisy NAS drives from the listening room. (The N31 does have a USB port—two, actually—which I used with Roon running on a Mac mini.) I also wished that the MBL’s reconstruction filter—the N31 offers a choice of three: Fast and Slow linear-phase filters and a minimum-phase filter— could be selected with the remote control.
At the start of 2020, MBL North America’s Jeremy Bryan let me know that an update for the N31 was available that would address these practical concerns. The N31 can now have a Roon Ready Input Module installed, either in production, which increases the price to $16,420, or retrofitted to existing N31s for $1062 plus the cost of field installation by a qualified technician.3 Bryan warned that some of the oldest N31s, including my review sample (serial number 0034), would have to be returned to the factory for the upgrade.

Nina Simone: Wild Is the Wind
By all accounts, Eunice Kathleen Waymon, aka Nina Simone, who passed in 2003, was a troubled person and a brilliant artist. Why she was not more acclaimed during her lifetime is a question several recent film projects have tried to answer. Did her fierce stand on civil rights lose her fans?
