The price has been drastically reduced. 2025/9/28 sales price 99,800 yen Maintenance completed! A basic tube preamp with a power supply built into the main unit. The sound quality is straightforward compared to the company's SA5.1 and SA3.1, and it is characterized by a bright and firm sound like a vacuum tube with good fluidity. In particular, the phono equalizer has high gain and is at a level comparable to that of a CD even when switching to a CD. *Turn on the power by slightly increasing the volume with the input selector in the RIAA position. When the power is turned on in the LINE position, shock noise is emitted when switching to the RIAA (only the first time) due to the original design. Also, after turning on the power supply, wait at least 1 minute and 30 seconds before turning on the power amplifier. You can see a feeling of use, such as appearance, dullness, abrasions, etc. (Kobayashi Hitoshi)
