width and open loop gain to provide uncompromised performance even at the 60db of gain required by a moving coil preamplifier. The instrumentation amplifier stage offers high common mode rejection, a noise-cancellation feature usually limited to transformer-based designs, while avoiding the serious limitations of those same designs.

A balanced pair of active RIAA equalization circuits follows the gain stages. The filter is built with 0.1%, plate style (non-inductive), thin film resistors and 1%, stacked film, polypropylene capacitors. This yields less than 0.1db deviation from the ideal RIAA curve. The user may switch an additional 20Hz high pass filter into the circuit. This fil- ter effectively removes the subsonic noise common to many turntable configurations. The filter conforms to the RIAA/IEC phono equaliza- tion curve.

Any potential for DC output from the phono preamp is nulled out by an active DC servo. The servo is implemented with low noise, high per- formance op-amps and film capacitors.

As with the rest of the components in the Nº32, the selection process involved many hours of controlled listening tests above and beyond the 9 usual measurements and lab work. Some examples of the selections in- clude:

•Signal path resistors are 0.1% tolerance, non-inductive (plate- style), thin-film parts.

•Signal path capacitors are also non-inductive (stacked construc- tion), either polypropylene or polyester in parallel polypropylene film caps.

•The preamp circuit board is four layer, Arlon™ N25 (an ultra high speed, low loss material) construction.

•Even non-signal path parts are film resistors and caps for best long-term stability.

•Low level signal interconnect is a flat conductor, Teflon™ insu- lated balanced cable, soldered at both ends.

•Low level signal relays are a rhodium contact, hermetically- sealed reed type, optimized for ultra-low signal levels.

•The entire module is fully enclosed in a conetic mu-metal shield box for ultimate low frequency noise isolation.
