Synergy IIi Stereo Preamplifier |
|
|
In 1996, the Synergy Stereo Preamplifier was released, creating a benchmark upon which other preamplifiers were to be judged. Debuting with an extremely compact and non-resonant chassis design with a separate AC power supply, the preamplifier immediately won praise for its outstanding presentation of the naturally recreated musical event.
In 1998 the Synergy was upgraded to Series II status, adding the flexibility and sonic benefits afforded by audio transformer coupling and a second pair of preamp-level outputs. This change in circuitry improved the unit's capacity to interface with diverse associated equipment.
In December of 2000, a new amplification board utilizing modern "small geometry" surface-mount technology gleaned from the Coherence II Preamplifier was designed and released for the Synergy II, lowering noise and distortion, and shortening signal paths dramatically. The current Synergy IIi presents a musical presentation that fully complements the current series of JRDG amplifiers and showcases their benefits without intruding upon the original source signal. Improved transient response, speed, and dynamics, increased transparency and neutrality, and an elevated level of detail retrieval and resolution combine to bring the Synergy IIi to a performance level significantly higher than was thought possible – without an increase in cost. The Jeff Rowland Design Group Synergy Series IIi - embracing our long tradition of applying state-of-the-art technology in the name of music.
