Having in mind that “analogs too have a lot more to go,” we expanded the product line-up of EA-1000, EA-500, EA-350, EA-300, EA-200 and phono amplifiers due to a non-feedback for lovers of analog discs.

This time, any small inexactness were eliminated as a compilation of semiconductor phono amplifiers, and the built-in MC transformer was newly designed with a special split winding structure that uses a high pure copper wire PC-TripleC as the secondary winding material.

The EA-550 will be released to experience a new level of sound along with a refinement on the circuit.
