• OTO SE Line / Phono (Signature)

    The Audio Note OTO SE is Audio Note’s entry level single-ended amplifier running in single-ended pentode mode. 

     

    While Audio Note is famous for those ultra expensive Ongaku’s, it may be the OTO that most consumers will be introduced to first. The OTO is, if not already, a modern day classic amplifier. To be viewed a classic in virtually any arena, a pre-requisite is for it to be able to stand the test of time. 

     

    Can your product still hold up against newcomers with new designs and ideas? The OTO SE has been selling for 16 years since 1992, and it continues to beguile, amaze, and sneak into the hearts of owners for its sheer beauty at replaying recorded material.

     

    The Phono version come with a tubed RIAA pre-amplifiers, while the Signature versions use more sophisticated wiring, components and transformers.

     

    Indeed, in a real sense the OTO is a different animal than a lot of integrateds that are designed as a cost-cutting measure at the design stage. This amplifier is in fact, dedicated preamp and power amp separates sharing one bigger box. Indeed, if you look at the innards of the M1 and P1, you can see very similar layouts.
