Jeff Rowland Criterion 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.
