The exceptional reviews are making thier way into the eyes of consumers. Here is a quote from the latest review on UltraAudio:
Purity Audio Design Reference receives Select Component award on UltraAudio.Com
The high frequencies were sweet, silky, airy, and delicate -- and, at other times, so revealing of information that my brain had to work hard to take it all in. The Purity References bass performance was among the best I've heard. The bass was deep, tight, detailed, and full, and rendered with lifelike clarity. The midrange was textured and present, with no hint of sounding soft or muffled. The palette of colors and timbres offered by the Reference was broad and rich. The Reference had see-through soundstaging in my system that was difficult for me to quantify -- stages seemed to extend past my rooms side and front walls, with images that were clearly delineated, dimensional, and well defined. In fact, the Purity Reference imaged with the best Ive had in my listening room

The Purity Reference is the linestage that was use in the Von Schweikert Audio room at RMAF 2010.
With 3 sets of balanced inputs, 3 sets of unbalanced inputs and 2 sets each balanced and unbalanced outputs, connection possibilities are vast. When an unbalanced input and is selected, the single still passes through the input transformer maintaining a low output impedance as well as the resolution and transparency transformer coupling is known for. Both balanced and single ended outputs are also transformer coupled
Volume, mute, source selection, absolute phase and balance control are selected both through the supplied aluminum remote handset and the front panel controls. (Balanced via remote handset only).
As with all Purity Series products, the remote circuit has been granted it's own dedicated power supply including a separate, stand alone power transformer as not to interfere at all with the analog circuit.
This Purity Reference is available for world wide sale.
