no longer for sale

This Basis is a demo unit but does come with our full 1 year warranty. Exceptional dynamics and speed with the richness of the 6SN7 dual triode from this enhanced Basis MKII linestage in a custom twin chassis hardwood design The 'Basis II' provides a silky smooth, clean, dynamic presentation with low distortion using a Class 'A' zero feedback circuit providing a low output impedance and high input impedance. If you have never heard the virtues of a 6SN7 based preamp, especially one designed by Purity Audio Design, you do not know what you are missing. Don't let the affordable cost of the Basis MKII fool you, this is a piece that is very much at home in the most elaborate audiophile systems and decors. This Basis II is built into a chassis slightly smaller than production units as can be seen in the side-by-side pictures. The actual unit for sale is the lighter color unit and is constructed of 3/4" solid Poplar. Rear panels are not laser engraved but are properly marked.
