The SATRI Circuit has reached a level that can never be reached with the conventional phono preamplifier design methods.

The concept of using the MC Cartridge as a direct current source overturns the general knowledge, and it holds an unrivaled position in designing a phono preamplifier dealing with minute signals.
In addition, by implementing an ultra-low noise Li-ion battery power supply enhances the excellences even further.

The reference version, “EQA-11R”, strictly employs the world best components such as Vishay Z-Foil resistors, Caddock Tetrinox resistors and Audience Aura Teflon capacitors, which results the performance that far surpasses the existing conventional phono preamplifiers.

Just as the sensation of listening to original master tapes, the natural analogue music can only be truly felt with the EQA-11.
