About the ZP3
The Decware ZP3 is a Zen Triode Phono Stage designed as an all-tube, single-ended Class A triode preamplifier using 12AX7 and 12AU7 tubes with no negative feedback and a large, vacuum tube regulated power supply. It employs a passive RIAA equalization network between two 12AX7 gain stages, resulting in an open sound with great depth. The power supply is over 500% larger than needed, using a 5U4G rectifier and OA3 voltage regulator tube to provide clean, stable DC power without solid-state components, eliminating noise and distortion artifacts. The unit weighs 13 lbs and measures 8.5" high x 7.25" wide x 14.75" deep. It has a gain of +42 dB, input impedance of 47 kOhms, output impedance less than 1 kOhm, and a frequency response from 15 Hz to 25 kHz. The ZP3 uses audiophile-grade components including custom transformers, poly film/foil capacitors, and gold-plated RCA jacks. It is designed primarily for use with moving magnet cartridges and can be optionally configured with step-up transformers for moving coil cartridges. The chassis is steel mounted on a hardwood base, with options for different wood finishes and anniversary or tape head mods. It has a lifetime warranty to the original owner and is highly regarded for its sound quality and build.
