Capri

The Capri Preamplifier offers a simple feature set for ease of use and a large, high-visibility display for volume level indication. The display can also be configured to turn off after 3 seconds when not in use.

As typical for JRDG products, the entire chassis of the Capri is milled from a solid, massive block of 6061 aluminum to provide a vibration-free and EMI resistant enclosure for sensitive audio circuitry.

Dual line-level outputs (balanced and unbalanced), balanced and unbalanced inputs, and preamp bypass inputs allow unprecedented compatibility with virtually any A/V component in both stereo and multi-channel installations.

The most commonly used features of the preamplifier can be controlled with an easy to use, six function, hand-held IR remote control.

A dual rate volume control allows precision level adjustments over nearly a 100 dB range. The volume control incorporates a permanently noiseless optical encoder that will always maintain its tactile feel, accuracy, and channel balance at all settings.

Optional high quality internal phono preamp modules are available.

Cosmetically and dimensionally, the Capri is the mate for the JRDG Model 102 Stereo Amplifier. The Capri’s sonic performance, interconnect capabilities, and feature set make it a capable preamplifier for any high-end system.

Criterion Stereo Preamplifier

On very rare occasions, one person's vision encompassing a life's experience and creativity will merge and come to fruition in a work of art unequalled among peers. Jeff Rowland proudly presents his Criterion Preamplifer.

The Criterion incorporates the most tried and proven concepts trailblazed by JRDG over the 25+ years of successfully developing the finest audio products available: battery power that provides the cleanest possible power source and isolation from the power grid, balanced circuitry, transformer coupling and much more. Additionally new ideas resulting in the further elimination of haze-inducing vibration are included in this no-holds-barred design.

Additional details are forthcoming, but words alone cannot adequately describe the sonic excellence of this unique product. It must be heard to comprehend this outstanding achievement.
