Purity Audio Design have announced the release of the Basis mk2 vacuum tube linestage. The Basis mk2 utilizes a Class ‘A’, zero feedback circuit based around a single 6SN7 dual triode per channel with a lower output impedance to allow better integration with a larger variety of amplifiers.

The Basis mk2 is said to “bring to the table a better sense of refinement over the original design with better resolution, transparency and detail retrieval. The larger power supply means dynamic impact remains intact during even the most demanding passages.”

Purity Audio Design also offers additional upgrade options for the Basis mk2 including a choke filtered, polypropylene power supply, signal capacitor upgrade and remote volume.

The Basis mk2 has a starting price of $2,500 US. A limited time introductory price is also being offered.
