John Curl's At It Again
By Larry Greenhill Posted: Jan 8, 2006
High-end amplifier guru John Curl, well-known for his early designs at Mark Levinson Audio Systems and for the Vendetta phono preamplifier—some regard this as the finest head amp ever made— was at the Alexis Park to discuss his latest design for Parasound, the JC-2 preamplifier. [The price of the JC-2 has not been determined yet, but will be somewhere in the vicinity of $3200.] John was particularly pleased to point out that he had worked with the same circuit-board designer from the Vendetta days. He also pointed out the preamp’s "D-core" power transformer, which has an oval core at right angles to the winding. John believes that this is much quieter than a conventional toroidal transformer. However, he had persuaded Parasound to omit a phono stage because even the D-core transformer wasn't quiet enough for him. That brought up an obvious question—would he reintroduce the Vendetta? Although nothing was definite, he noted, "I'll probably have to do something because everyone is bugging me to bring it back."
