We have prepared a special cable so that the power amplifier can be used alone! Maintained. 230V specification (it is possible to operate with a 100V power supply by using the included step-up transformer). With this, it is also possible to build a system with a Marantz 7 masterpiece preamp that you will dream of at least once. You can enjoy an excellent, thick vintage sound with a good QUAD tone and a relaxed sound. The relaxed expression unique to mono is also attractive, and you can enjoy the deep sound unique to vacuum tubes. If you have a QUAD22 preamp, you can use it with a normal 2+22 system (Kojima Yosuke)
