Review
Imperssive well managed 300B amplifier. Good respond, good dynamism. Quiet rare excellent extensive range as 300B amp. Not only tighten tone wiyout distortion, but also demostrates tenacious driving force. Low noise, minimum distortion in sound. Yoshiba selected alternating current ignition for superior sound quality, it should be contribute improvement of reproducibility. The texture and feel of chamber music is fespecially ascinating. Natural timber of string instruments containes not only quiet dense and muscular, but also expess ideal moisture and glamor. Good separation of each musical instruments, amazing resolution of individual harmony without any turbidity.
The resolution in Orchestra was awsome, tutti did not collapse even loud volume, furthermore there were no thorns that stung my ear, but comfortable at peak volume.
Clarity bass, rich, more details and beautiful sound colours..Piano and woodbase in Jazz was a fundamental approach in lowering center of gravity, rich in details and emotionally affecting. Pianosolo was queit effective for transparency and high speed, smoother tonality and deeper low end.
