Maintained in 2014! The heavyweight power amplifier for the threshold. It has a solid momentum and strength, and large speakers drive well. You can enjoy the thickness, texture, and air feeling unique to this age. The appearance is somewhat dull, but it is a good class from the year (Oikawa Tetsuji)
