We have a few higher end products available at let go prices. Please see our outher ads here at Audiogon.

The multi award winning Reference linestage continues to get better. The Purity Reference is a Class A, transformer coupled balanced linestage and is the result of years of intensive research directed at attaining the most accurate reproduction of recorded music. Unique topology and application of the most advanced technological resources and processes bring the Purity Reference to a threshold of excellence in sound reproduction. To add to the main features, the Purity Reference utilizes transformer coupling at both the input and output. Transformer coupling output results in a low output impedance making the Purity Reference a versatile unit that is capable of driving both solid state and vacuum tube amplifiers with input impedances as low as 600 ohms. Extraordinary transparency of perceived sound which in turn assures the recreation of a three dimensional soundstage.
