I first met Musical Fidelity's founder, Antony Michaelson, in 1978, when he was running tube amplifier manufacturer Michaelson & Austin. I still have an M&A TVA-10 amplifier, which was designed by the late, great Tim de Paravicini. Soon after Antony founded Musical Fidelity in 1982, he employed de Paravicini to design the A1 integrated amplifier.
The A1 was a slim solid state design with a class-A output stage that output 20Wpc into 8 ohms. By contrast, the massive, dual-mono Musical Fidelity Nu-Vista 800 integrated amplifier, which Michael Fremer reviewed for Stereophile in November 2015, featured nuvistor tubes for its small-signal circuitry, coupled with a solid state, class-AB output stage that could deliver 330Wpc into 8 ohms.

About four years ago, the stand-alone tonearm market went through a bit of a crisis. First, in December 2019, SME announced that it would stop selling tonearms separately, effective immediately. From that point on, SME tonearms would be available only in combination with SME turntables. . .
Five months later, in May 2020, we received the second blow in this double whammy of bad tonearm news. That's when the Ichikawa Jewel Company of Japan, maker of Jelco tonearms, announced without warning that they were shutting down operations, closing their doors for good. They blamed a combination of an aging workforce, worn-out tooling that needed to be replaced, and the coronavirus pandemic. . .
We lost two key players all at once, but it's not as if we suddenly had nowhere to turn for tonearms. Turntable manufacturers like Acoustic Signature, Clearaudio, Origin Live, Pro-Ject, Rega, and VPI all sell their tonearms separately . . . A number of smaller tonearm specialists have popped up in recent decades: Acoustical Systems, Graham, GrooveMaster, Kuzma, Reed, Schick, Schröder, and at the ultrahigh end, Swedish Analog Technologies. Now we can add Korf Audio to the list.
