THE ABSOLUTE SOUND--

Parasound Halo JC 3 Jr. “What happens when Parasound once again taps John Curl and his partner, circuit board designer Carl Thompson, to make lightning strike twice at a cost that’s half as much as the great JC 3+? The JC 3 Jr. is what happens. But there has been no scrimping on features and configurability. Junior conveys a warm ambient flavor, an openness rather than a constriction within the hall. Wind and string transients are smooth and naturalistic. A phono preamp that will stand the test of time.”
