One privilege of being a Stereophile columnist is the opportunity to cover products from smaller, less well-known manufacturers, including those that don't have wide enough distribution to qualify for a full review. One such company is Victorville, California–based Paradox. I'd never heard of them until I received an email from Terence Robinson, the company's owner. The email included a description of a phono preamplifier that so intrigued me that I asked for a review sample.

One reason Stereophile publishes a FollowUp is when the original review leaves an issue unresolved or where further thoughts would be useful. Such was the case with the magazine's March 2022 issue, which had followup reviews on the iFi ZEN CAN headphone amplifier and ZEN DAC Signature V2 D/A processor ($599/pair). the Pro-Ject Phono Box RS2 phono preamplifier ($1999), and the Canton Reference 7K loudspeaker ($6995/pair).
