This is Ikeda's first introduction of Hi-Fi's boost transformer. Thorough noise countermeasures are taken by adopting a floating structure that floats the internal transformer body and mu metal shields that are independent on the left and right. Even fine signals are amplified without being spoiled, the details of the music are highlighted, and the sound is three-dimensional. The set with the company's IKEDA9 series brings out 100% of the features of ultra-wide range and high resolution, and in matching with the SPU, subtlety and strength are mixed at a high level, and the musical luster of female vocals etc. stands out. If you are an IKEDA9 series owner, please give it a try!
