Natural Sound Integrated Stereo Amplifier (1980-82)
Yamaha in these series had excellent phono preamps built in, it was rare at the time they were launched to see something with a modern look have a 6-position phono selector and a DISC Direct… switch. for LPs. Good yamaha!!!
The sound is clean and powerful, with pleasant dynamics, but a little shy on bass, which may not be enough for some tastes or types of music… it does justice to the claim of a natural sound, typical of yamaha too, it doesn’t have that warm, strong sound of the amps from the 70s.
This series was also known for having a weak point, its sliding selectors, it’s rare to find one without problems with these selectors…
In short, they’re beautiful, powerful amplifiers with a natural yamaha sound.
