    Audio Research Reference Phono 3SE

    Audio Research Reference Phono 3 SE is a tube phono corrector. Phono 3SE has a design developed from scratch, absorbing the successful findings from Reference Phono 2. In fact, the Reference Phono 3SE is a synthesis of developments from the entire Reference series. An additional gain stage allows you to obtain the linearity of gain characteristic of the Reference 10 and Reference 6 preamp models.

    Audio Research Reference Phono 10

    The Reference 10 is powered by a fully dual mono circuit. Dual, separate low- and high-voltage transformers are used for each channel; a dual mono stabilization circuit (one 6H30 and one 6550WE per channel), a dual mono gain circuit (four 6H30 per channel), and a powerful electrolyte bank.
